Question

What is an echo? what factors are important to get a disstinct echo?

Answer 1

Answer:

An echo is a sound which is caused by a noise being reflected off a surface such as a wall. In easy words it's the repitation of sounds produced by us.

The factors required to get distinct echo are as follows:-

• The intensity of sound should be such that the reflected sound reaching the ear is sufficiently intense to be audible.
• The minimum distance between the source of sound and the reflector in air must be 17m.
