Standing waves can be produced

Options

A. In a string clampedat both the ends
B. In a string clamped at one end and free at the other
C. When incident wave gets reflected from the wall superimpose
D. When two identical waves with aphase difference ofn are movingin the samedirectionsuperimpose

Answer

A, C

Explanation

Standing waves can be produced by superposition of two coherent waves travelling in opposite direction. Here on a clamped string incident and reflected wave can produce stationary wave by superposition on each other.
