Question

Experiment to find speed of sound in air using echo

Answer 1

Answer:

This rate is adjusted until each clap just coincides with the return of an echo of its predecessor, or until clap and echo are heard as equally spaced. Use a stopwatch to find the time between claps, t. Make a rough measurement of distance to the wall, s. Thus the speed of sound, v = 2 s/t in the first case.
