Answer:
The different speed of the sound waves in water and in air.
Explanation:
Sound waves are defined as the mechanical waves that are resulted from the vibrations back and forth of the particles of the medium through which the sound is moving.
The speed of the sound is faster in water than in air. Sound travels much faster in water than in air. In air the speed of the sound waves is 343 meter per second while the speed of the sound waves in water is 1480 meters per second.
