Answer 2

Answer:

An echo is heard sooner in water as compared to air because the speed of sound depends on the elasticity of the medium. The more elastic a medium the greater will be the speed of sound and vice versa. So water is more elastic than air. The sound will travel faster in water which is why, we heard an echo sooner in water as compared to air.
