To Find the Focal Length of a Convex Lens by Two-Pin Method | Class 12 Physics Practical
In this video, we explain the two-pin method to find the focal length of a convex lens, a very important experiment for Class 12 Physics board practicals (CBSE / ICSE).
The experiment is based on the no parallax condition, where object pins and image pins are aligned accurately to determine the object distance (u) and image distance (v). Using the lens formula, the focal length of the convex lens is calculated step by step.
This video covers the experiment setup, procedure, observations, calculations, ray diagram, precautions, and viva questions, making it perfect for board exam preparation and last-minute revision.
👉 Watch till the end for clear explanation and exam-oriented tips.
