When you yell in a canyon you hear an echo of your voice Why is this?
When you yell into some canyons, after some delay, you can hear your voice echoed back to you at a lesser volume. This is caused by the energy of the soundwaves bouncing off of the canyon walls and returning to your ear, instead of the energy being dispersed or continuing away from you.
What will happen if you shout into the canyon?
If you shout into the Grand Canyon, your voice travels at the speed of sound (340 m/s) to the bottom of the canyon and back, and you hear an echo.
How deep is the Grand canyon at a spot where you can hear your echo5.2 seconds after you shout?
Answer: The depth is 884 m.
How far away was the canyon wall that produced the echo?
2 Answers By Expert Tutors. In 3 seconds, the sound will have traveled 3300 feet. Since the sound’s movement is a round trip, the canyon wall is 3300/2 = 1650 feet away. In 3 seconds, the sound will have traveled 3300 feet.
Why can you not hear the echo if you stand 10 m away?
Why can an echo not be heard if you stand 10 m away from a wall and shout facing it? We cannot hear the echo because the time difference between the original sound and reflected sound will be less than 1/10th of a second. So, we are not able to distinguish between the two sounds.
How far away is the canyon wall?
Since the sound’s movement is a round trip, the canyon wall is 3300/2 = 1650 feet away.
Why can you not hear the echo if you stand 1 0 m away from a wall and shout towards it?
Question: Why can you not hear the echo if you stand 1 0 m away from a wall and shout towards it? This is because, distance travelled by sound in 1/10 second = speed x time = 340 m/s x (1/10) s = 34 m. Thus, we cannot hear the echo if you stand 10 m away from a wall and shout towards it.
Why can you not hear the echo?
Sound waves get reflected by hard surfaces such as walls, mountains, etc. The reflected sound reaches us very fast and has almost the same magnitude so we are not able to hear it distinctly so we can say that there is no echo happening.
