An Echo.
Echoes means the repetition of a sound caused by the refection of sound and waves.
No, they can be caused by standing waves, but they move
Sound Waves
The word echo means a repetition of sound produced by the reflection of sound waves. The origin of this word is Latin.
Light travels in waves, and sound travels in waves. However, sound waves and light waves are very different, and it is important not to confuse the two. Light travels in electromagnetic waves, and sound does not. Sound waves are caused by vibration.
The vibrations caused by sound waves onto your eardrums are pressure compressions and rarefactions.
An echo is a sound caused by the reflection of sound waves.
Sound waves and water waves are similar in that they are both caused by vibrations and carry energy. They are different in that a sound waves are three dimensional, while water waves are just two dimensional.
Echos are caused by sound waves bouncing off walls or objects
Some sound will get through, which is why you can hear sound coming from the nest room. And some sound will also rebound, which is why an echo is often formed in mountainous areas.
Sound waves are caused by vibrations and travel as longitudinal waves which cause by the vibration of the molecules in air (the molecules dont actually move)
The modern definition of echo is the repetition of sound produced by the reflection of sound waves from a wall, mountain, or other obstructing surface.
