Quack Of Duck

An Echo is the reflection of  sound when the sound strikes a hard object and returns to the listener.We have often observed it when we shout in a closed ,empty room.A true echo is single reflection of  sound.

FACT:All kinds of sounds produce an echo but the quack of duck never produce an echo.
