a sound or series of sounds caused by the reflection of sound waves from a surface back to the listener.The two conditions for echo to be heard are:1. The minimum distance between source and reecting
surface should be 17.2 m .2. To hear a distinct echo, the interval between original and reacted sound must 0.1 second. Bats cannot see still they catch their prey as they produce ultrasound. This ultrasound is reacted
back to the bat if their is any obstacle in its way, and thus bats catch their prey.
