The bouncing of a sound wave off a surface may result in an echo being heard.
It's called an echo.
The bouncing of light off a surface is called reflection. When a light wave is bent it is called refraction.
If you think of light as made up of small, elastic particles, then when they hit a hard surface, they will bounce off and travel in another direction. This is analogous to a basketball bouncing off a floor. However, the particle nature of light has been disproven. A more accurate description lies in the wave or particle-wave duality nature of light.
It has to have a hard surface to bounce off of. :)Apex Not necessarily. The reflector is the surface of a medium of greater density than that through which the incident sound travels, and it can be the surface of water, or a density-boundary caused by sharp temperature or salinity differences in the sea.
Part of the energy of a sound wave is absorbed when it comes in contact with a surface, and the rest of that energy is reflected. A soft surface (such as carpet) will absorb much more of the sound than a hard surface (concrete), but the hard surface would still absorb some amount of energy.
An echo is a sound wave that has reflected off a boundary

An echo is a sound wave that has bounced off a surface
When a sound wave strikes a smooth hard surface the wave bounces off. This means that the wave is deflected.
Waves bouncing off an object is called reflection.
Waves bouncing off an object is called reflection.
This is called reflection of sound. It's like a sound wave bouncing on a trampoline.

An Echo-echo-echo-echo! The answer is Echo
