What is echo ?
Answer :
If you stand in front of a hill and light a firecracker, you will hear its sound twice. First you will hear the sound coming directly from the firecracker, and then you will hear its sound reflected off the hill.
The sound that is heard after the first sound due to the reflection of sound at a surface, is called echo. You must have heard your voice echoed in large empty halls also.
It is happening so because of the reflection of sound of your own.

Echo is the reflection of sound.
Explanation:
The sound waves left your mouth, traveled through the air, hit a hard surface, such as a wall, and then bounced back again, causing you to hear the sound again.
