Standing waves on a string and Melde's experiment
A string driven by a vibrator. Tune the frequency to find resonances, count nodes and antinodes, and verify f_n = (n/2L)√(T/μ). Change tension, length and linear density.

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.
