What is the term echoes defines us.
Friends have you all sometimes heared your voice back when you shout facing front to a big and a hard object such as mountains,dams etc.The voice which came back to you like a boomerang after you stopped producing sound are called echoes,which are form due to reflection of sound by striking with an object and coming back to the source of sound.And echoes doesn't produce when we shout facing infront of a smooth surface such as clothes,walls,woods etc because these objects have the ability of absorbing sound.
