Answer 2

Hey dear❗️❗️

⬛️Here is the answer, you needed..

If you call out your name in the direction of a vertical, bare Rocky wall, you will hear it again after sometime. An echo comes because the sound waves are reflected back from the wall. When sound is produced in enclosed spaces, such as churches and gymnasiums, multiple reflections build up and blend together. This phenomenon is known as reverberation.

Hope my answer will you !!
