The answer is pie.

If someone is standing in the canyon while you shout, the sound waves will bounce off the canyon walls and create an echo. The person in the canyon will hear the original shout followed by the echo, which can create a cool and amplified sound experience.
Han stands at the rim of the grand canyon and yodels down to the bottom he hears his yodel echo back from the canyon floor 5.20 seconds later assume that the speed of sound in air is 340m/s how deep is the canyon?
If Polly hears her own echo 4 seconds after shouting, the total round-trip time for the sound wave to travel from Polly to the canyon wall and back is 8 seconds. This means the width of the canyon is approximately 2,720 meters (8 seconds multiplied by the speed of sound, 340 meters per second).
Yes, the "a" in canyon has a short vowel sound where it sounds like "kan-yuhn".
It made a big sound. It did not make a big sound the Glen Canyon Dam changed the ecosystem of the Grand Canyon. I had the same question for an assignment that I had for school. I found the answer in a book that I had. Hope it helped!
An echo is heard when a person shouts in a canyon because the sound waves reflect off the canyon walls and back to the listener's ears with a slight delay. This delay is what creates the perception of an echo as we hear the original sound followed by its reflection.
An example of an echo is when you shout in a canyon and hear the sound bounce back to you. This occurs because the original sound wave reflects off the canyon walls and returns to the source.
It means that the sound wave goes toward the canyon wall, and then a wave carrying part of the energy comes back from the canyon wall. The remaining energy will be absorbed or will pass through.
No, they can be caused by standing waves, but they move
The distance to the wall of the canyon is 340 meters. This is calculated by dividing the total distance sound traveled (twice the distance to the wall) by the speed of sound (170 m/s).
It would take approximately 6 seconds for the sound to travel to the wall 360 feet away and bounce back as an echo. The speed of sound in air is about 1,125 feet per second, so the total distance traveled would be 720 feet (360 feet to the wall + 360 feet back). Divide this distance by the speed of sound to get the time, which is roughly 0.64 seconds each way, totaling about 6 seconds round trip.
