To find the focal length of an Objects On Convex lens No Parallax (two pin method ) #a2zpracticals

Hello everyone, how are you all? I think I will definitely have to keep a close eye on those extremely crucial practicals in my life. You have brought your physics practicals here for the students. That is also known as the NO PARALLAX METHOD. There are many practicals for the Ab no parallax method. These practicals are yours, kid. It's the U by V method. If it's UV, then we'll check it. Just listen carefully right here Our aim in_august physics experiments is To determine the focal length of an object and a convex lens using the two-pin method By the two-pin method We'll do it using the 2-pin method then. We will find the focal length of any object. How will it be? Look very carefully Hume will have some apparatus installed here. An optical lens will be attached. The lens holder will be installed. A pin holder will be installed. A convex lens is used. And half-meter scale The formula we will use Is this it? Then I'll tell you. First, listen carefully How will the practicals be conducted for you? You must look at it very carefully What exactly is the child doing here? I'm going to tell you something dear and small Here you have an optical bench. The child is not on the optical bench. I'm placing a pin here. What do you keep? Yes Keep the pin Here, right here Place a convex mirror What do you keep here? Convex mirror That's what happens We'll keep another pin here. Okay? We'll place another pin here. Alright Your convex mirror is ready. It's done. We call it that. Object pin What do you mean? Yes Object pin And the one who is here on this side Doosra pin People call it that. Image pin You'll understand it right away now Image pin It is so. Listen to Dhyan Yes, convex lens the That is a pin object. Or is that your image pin? It is so. Just look here You are not Absolutely right here Matlab, I'm not here from here We will observe it repeatedly. We will see. Who is his parallax? Remove hum What is it? He is the inverted image of me. This is where it is built. Here An inverted image is formed here. But that inverted image With him, I am not He moves around so carelessly, so recklessly. To hum, this parallax I've left it behind, I've let it go Between this and that Like Object Object pin Oh Convex At the center of a convex lens If you are at a distance You are measuring Isko u se Represent to chart A convex lens Oh The middle of the image pin dumped Are you measuring? This one In the sea Represent to chart Which one? Represent to draw Banta Boy In the sea Represent It is so. By this way Those are the practicals. Those who come to watch here Here are the practicals for you. Bataunga Here it is A little bit Give me your attention Here it is Your observation table It's the U by V method. It is so. Distance of the object Distance of the image What is the focal length? It is so. Where are we with the result? Here, focal length What are you going to do? Find out It is so. Without the parallax method Alright Main iske experiment ko What are you doing? You're starting now Students This is your experiment And in this experiment We are going to find out Focal length Of this convex I will explain. Since you keep having doubts No When I do this When adjusting What is it? Your image What will happen? Inverted AUR What is a bataung? This one is for the other one Absolutely with me Move Honge Your naked eyes Absolutely your own self It should be facing forward It is so. When together with you Move hot That's when it happens Your parallax method You probably don't understand it. Alright Hurry up, hurry up, here! Come here You have placed the instruments on So machha Main ek ye White color screen It's Raksha Bandhan. It is so. This is an instrument. Ours It is so. Here This is our object Fish is here. What do you call this? This is the object Peen It is so. There's some cm here My scale It is written. After that I have entrusted it. Here Convex mirror Fish That's my convex It's a mirror. It is so. After that I have kept it. Image Peen It is so. All of them What is work? How do you do it? All these things Fish I'm here right now Explain karunga Since in this experiment We are going to find out What focal length Of this Convex mirror OK Alright You start the tab Your this experiment Fish What do you usually do? Your The screen is an object. It is so. Main isko I'll give you zero. And when he saw this It is a convex mirror. Fish This is 70 cm. I will give it to you. Here You can see the scale here. It is so. You are absolutely right here You He must be looking deeply. Is deep wali line Where to touch? Touch 70 Here it is 70 cm Maine It has been kept here. MATLAB First reading Fish Main 70 cm wide I will start. Another thing Tell me please From here Up to this point You have distance Nikala So machha Isko u se I represent And from here Image peen In the middle of the road Distance If you have Nikala To it In the sea Representing Fish In the sea I represent What will you become? What's this It's an object. Fish It's creating an image. On the convex mirror Exactly the opposite way That's why It is ours. Convex mirror Convex mirror Pehachanne ka A very The best way is this. Darkness MATLAB Beech me It's thick. On the other side Tell me, please. Its curvature I'm feeling dizzy. It is thin. OK Alright Like this one Inverted image will appear We will see. About him and his matter This image of mine With the pin With image pin We We will match As soon as We will match Fish This is our It will happen. No parallax method Matlab we all Parallax Co We will remove it Here Alright We start now Your this To the distance To whom? That's a long way. Your We will do this ourselves We represent That distance Your Convex lens Aur mirror The middle of the image pin We will do this ourselves We will represent you Let's start the Practicals now Fish I'm here right now You 2 to 3 reading I'll show you. How, how Your readings I am telling you Where should I keep it? Main usko It's the seth's property. Convex mirror Certainly 70 cm wide It has been arranged. Or is it mine Image pin Alright You The Kisa Late Here Main Key Signal To Abo He le Lapt Key Kit I To And what exactly is a parallax? Now, let me start showing you. What can you possibly see here, child? That image pin here And here, the inverted pins being formed If I take this with me to Agar If I write it, it won't work together with another one. Look, I'll show you left and right. Look, as I'm leaping, that pin is running away over there And come here, this pin is over here As I The pin is running away over there. Write it down, they will grow taller. Here, the light is shining. I'm talking to you from the moon. So, are these the parallax or not? I've already taken care of it from Tho Jano. So you can see You can see it As if life itself Yes, I have noticed this here — the Distance is 70. So, this U-shaped sand here, how much is it? 70 is correct, okay At 70, the V-shaped sand that's coming my way—how much is it coming? So I quickly make a major adjustment. So from 70, the child From 70 onwards So how much do I have here? This is 20.5; it matches here. 20.4 It's tied at 20.4. So this from here to here This distance between the convex mirror and the image is called V. This is 20.4 So how much will I get here? 20.4 First I write down everything, then all the stuff I'll tell you everything, come on What you need to do now is convex mirror I need to be 60, that's fine What should I do to reach 60? You can see this; I'm moving up to 60. When I take it to 60 So if you look back from here, you'll see It will not become a barrel anymore. I'll show you. When you press Left and Right, it's okay You will notice that I have now adjusted it. I'm showing you this in the camera now No, I won't tell you what I'm showing. Now you can see here that What's this, your image pin, kid? And this is yours, this very thing So the next one of my readings that came in is for 60. So this 22.7 Now I'll draw the third one for 50 What do I need to do for this? So, this child, this is my convex lens I'll shift this to 50. So, 50, that's what I said here. 50 Here So where should I place the convex lens? I'll shift at 50, I'll shift at 50 Now, but when you set it to 50 So when your image is pinned, kid It will now continue to run in parallel, okay? When you are in the mud Late and right if you move So, check out the inverted pin Here And the image pin is correct Your both don't get together properly, right? He goes to the belly, he comes to the belly, he goes to the belly The broken full reflection meets you, looking to see you So we'll go with no parallelism Coming to the method You are not allowed to do this right now. You will be able to see the method here. I have the image pin and the invert pin. Pierlex The soup is very spicy, and we can see your eyes watering. From the image of the girl Distance between the convex lens that is ours 25.2 25.2 We take this right here, okay? It's taken exactly on the line, okay Ashna is coming. That's when it finally comes together. 25 2 is there, then I will now go to his house and beat him up. 45 2 Pad's Idhitiye We greet you with Namaste and offer our heartfelt respect. Here. I took it to 40. At 40, I took this and left. The child who came back with me is this one. It's all messed up again. It messed up the Paralex, this talmas got twisted two times, so fix it. I opened it again from my own files. You are in bliss. This was wrong. What will we do? We'll stay put and stay right. Now we take the distance, fata fat You know, the child is between this and this. I took 40 distance, correct? This is the 40th one, and the second one V means Convect Lens Let's check the distance between them to see how much it comes to. Here comes our child. 28 28 is coming So we will write here 28 Last one more reading I'll kick you out for 30. For 30, please Convect Lens It will have to be written as 30, then mine Here it is, 30. Here it is, 30. So I'll just write it down here I've reached 30 It should be exactly on this line 30 now looks at 30 That which we have here It's an image file. Where do I have to keep this? That I didn't get any parallel at all Alright, I'm setting it up, break it open, this one Finally, ours It's already been done, no parallel play Wherever you have the camera that these two pins Image Pin and Invert Pin What is happening here is certainly not both. I'm fine, and you? So from this, we understand that this is its Parallax removed. Let's go. If we calculate the distance for this, the distance that comes out will be He will come. Jokingly You've been wiped clean, this way 38, 38.5 Okay So the value of V that will come today 38.5 Writes down the value of Thattapit and then leaves. So the value of V that will come out will be 38 points When I saw this Convex Lens and This Object Mirror When the distance between the child Listen, I'm reducing it. So, what was your V value? Convex Lens and The distance between the Image Pins It gradually began to increase. So I will tell you about every single thing I'll show you right now on the smart board. How Calculation and Results Your hand boot's I'm starting. Something like this I received the reading, I sent you the practicals I had shown it through action. Now we need to calculate the Focal Length How do we calculate the focal length? So we all have to be multiplied And I'll show you by doing it. How do you calculate the first one's focal length? What do you have? How much do you have with you? 20.4 Divided by U plus V You have 70 with me. I have 20.4 with me. Now you all Divide and conquer. 90.4 will come today Multiply It needs to be multiplied by the first one. Multiply 70 x 20.4 1428 Divided by 90.4 GPLv3 1428 Divided by 90.4 15.79 You Alone You Subcrase Poker Linth So how will you get out of this, kid, by pushing everyone aside? However many numbers you want to divide it by, just do it, as you see. 15.79 but 16.46 but 16.97 but 16.47, 16.47 but 16.86 divided by what number is 16.86? 16.5 But Will come today 16.5 But What is this, what will it fit in, measured in centimeters?
