Echoes are sound waves reflected back.
They can bounce of smooth, hard objects, 
the same way as a rubber ball bounces off the ground.

An echo is a series of sounds caused by the reflections of sound waves from a surface. For example, you can clap and it will make an echo since the sound waves would hit an object nearby, causing an echo.
