echo.
An echo is a sound that bounces back to you after reflecting off a surface.
The reflection is vibration because sound is equal to vibration
When a sound wave bounces off a hard surface, it can be called either an echo or a reflection. Both terms refer to the phenomenon where the sound waves are reflected back towards the source.
When a wave hits a surface through which it cannot pass and bounces back, it undergoes reflection. The angle at which the wave hits the surface is equal to the angle at which it bounces back, following the law of reflection.
When sound reflects off a surface, it is called an echo. This occurs when the sound wave hits a surface and bounces back towards the source, typically creating a distinct repeating effect.

Sound wave reflection occurs when a sound wave hits a surface and bounces back. The factors that influence the reflection of sound waves include the angle of incidence, the nature of the surface, and the frequency of the sound wave.
When a bullet bounces back after hitting a hard surface, it is called a ricochet. Ricochets can be unpredictable and dangerous, as the bullet's trajectory can change after hitting a surface.
Sound that bounces back is called an echo and they are formed when sound waves are called a bellend.1. Sound travels in waves2. These waves bounce of nearly everything3. Sometimes these waves get absorbed or run out of energy4. If you are in a big room/place with nothing in these sound waves bounce around and end up coming back to your ears!
reflection
That is called reflection. When light hits a surface and bounces back, it forms an image of that object that we can see.
You pluck a string, the string vibrates, the sound waves enter the soundhole, bounce off of the wood(different woods result in different tones)and it all bounces back out of the soundhole.Please see the related link for details.
