Sonometer: frequency, tension, length laws
A string stretched over a sonometer: find the length that resonates with a tuning fork (paper rider jumps off) and verify f = (1/2L)√(T/μ), f ∝ 1/L and f ∝ √T.

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.
