You shout “hello” into an echo chamber that is 250 m long. Assuming that the speed of sound is 340 m/s , how long will it take for you to hear your echo? We are going to pretend that there is no damping of the sound and this echo chamber is perfectly reflective in only 1- dimension ( Horizontally). Hint: how far does the wave travel before it reaches you?
