Diffraction pattern using a laser beam || activity 05 grating || #class12thphysics @a2zpractical991

This video demonstrates a physics experiment using a Helium-Neon (HeNe) laser and a diffraction grating to determine the grating element. The presenter explains the setup, the process of marking intensity points on graph paper, and the mathematical calculations required to find the grating constant based on the diffraction angles.
