Question

Describe the experiment to determine the speed of sound by the echo method

Answer 1

Explanation:

This method involves measuring the time taken for you to hear an echo from a sharp clap. You stand a long distance from a wall, clap, and listen for the echo. The distance travelled is twice the distance from you to the wall (because the sound has to travel to the wall and back).
