A bounced sound wave is acalled an echo. You can hear these echos when you yell into a cave or a crevasse or an abyss.
clap and listen for the echo an echo is just a reverberation of sound bouncing off something solid about 17 meters away and returning will produce an echo. You can't litterally find an echo just clap and listen for one.
Voices echo because the sound waves create by the human voice bounce off an object and reflect back to the original source. Echos will usually take place in wide open spaces because the objects are far apart, thereby the sound takes longer to bounce off an object. When in closed spaces that absorb sound like a voice over booth, you will not hear any echo as objects are closer and the sound is being absorbed by soundproofing.
Geologists use echos to search for oil by conducting seismic surveys. They send sound waves into the ground and these waves bounce back or echo off the different layers of rocks beneath the Earth's surface. By analyzing the speed and direction of these echos, geologists can map out the underground structures and identify potential oil reservoirs.
In the broadest sense, an "echo" is a reflection. If it happens, then something that was sent offin that direction comes back in thisdirection.When an echo of sound occurs, you shout at the side of a mountain, the sound reflects off of it,and you hear your own voice coming back to you from the mountainside.When an echo of an electrical signal takes place in an unbalanced 2W/4W hybrid in a microwave siteor telco central office somewhere, often in a foreign country, you hear your voice coming back to you,delayed, over the telephone, which can be very confusing and the conversation usually doesn't continue.Light can also reflect from things, whether the things happen to be smooth or rough.When the light from a flashlight echos (reflects) from the floor in a dark room, the result is thatyou're able to 'see' the floor.When the light reflected from your face echos again from a smooth surface and heads back in thedirection of your face, you can 'see' the image of yourself reflected from the mirror, the puddle,or the smooth side of the toaster.

An echo is a sound wave that has reflected off a boundary
The Echo was produced from 1999-2005. Known as the Toyota Platz in Japan, and exported as either the Echo or Yaris. The Yaris is still in production today, now in its 3rd generation. The 2nd and 3rd generations have been redesigned, yet still have many of the same features as the Echo.
Poor sales. The Echo was replaced with the Yaris.
Bat's use echo to find there prey since they have poor eye vision.
Echos are caused by sound waves bouncing off walls or objects
Through echo-location. They emit high-pitched sounds and by listening to the echos they get a kind of radar picture of their surroundings.
to produce an echo, the sound wave bounces off a surface and then comes back
