Young's double slit experiment
Shine monochromatic or white light through two slits. Change wavelength, slit separation, screen distance and slit width; measure fringe width β = λD/d and see the diffraction envelope.

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.
