Reflection and transmission of a pulse at a boundary
Send a pulse to a fixed end, a free end or a junction of two strings; see inversion, no inversion and the r and t coefficients.

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.
Topics: wave reflection · fixed end · free end · impedance · transmission
