884 m deep is the grand canyon at a spot where we can hear your echo sound 5.2 seconds after we shout.

speed of sound = 340 m/s

Time echo= 5.2 s.

h = depth of the canyon.

Because the sound of our voice travels to the bottom of the canyon and back to our ear, the total distance traveled is 2h.

distance = velocity × time.

2h = (340 m/s)× (5.2 s) = 1768 m

h = 884 m

The phrase used to describe the sound is called an echo. It is based on the idea of sound reflection. After the original sound has faded, we hear the reflected sound.

Additional requirements for clearly hearing an echo are: The reflector's size must be sufficient in relation to the sound wave's wavelength and the emitted sound's power should be high enough to make the reflected sound noticeable.
