Single slit diffraction
Light through one narrow slit. See the central maximum twice as wide as the others, the minima at a sin θ = nλ, the intensity envelope sinc², and how width, wavelength and screen distance change the pattern.

What you do in the lab
Change the controls and watch the physics behave in real time in 3D. Live readouts and graphs show the numbers behind it, and the Learn tab has the theory, procedure, observations and viva questions. Works on a phone or a laptop, in English and Hindi.
