An echo is an example of reflection, which occurs when a wave bounces off a boundary. In the case of sound waves, an echo is produced when sound waves reflect off a surface and return to the listener.
Reflection is responsible for the echoes of sound. When sound waves encounter a surface, they bounce back, creating an echo.
Diffraction is responsible.
It is called an echo.
When a sound wave hits a surface and reflects back towards its source, it creates an echo. The time delay between the original sound and the echo is determined by the distance between the source and the reflecting surface. The intensity of the echo is typically lower than the original sound due to energy losses during reflection.

In general waves can: Wrap around the obstacle. This happens when the wavelength is larger than obstacle size. Bounce back as an echo off the obstacle. This happens when the wavelength is shorter than the obstacle size. Be absorbed by the obstacle. This occurs when the natural frequency of the obstacle matches the frequency of the wave...so-called resonance. Pass through the obstacle. There are several ways this can happen. But visible light passing through a glass window is one example.

The reflection of a sound wave is called an echo. When a sound wave encounters a hard surface, it bounces back and can be heard again, creating an audible reflection known as an echo.
An echo is a sound caused by the reflection of sound waves.
An echo is the reflection of sound waves off a surface back to the listener, resulting in a delayed repetition of the original sound. For example, if you shout in a large canyon, you may hear your voice echoing off the walls.
A reflection is the bouncing back of sound waves off a surface, while an echo is the repetition of sound caused by the reflection off a distant surface. So, a reflection can contribute to creating an echo by bouncing sound waves off a surface, leading to the perception of a repeated sound.
