Statement-1 `:` In under water communication, sound waves with low frequency are better than those with high frequency.
Statement-2 `:` When sound pressure amplitude exceeds the atmospheric and hyrostatic pressure, it sets up eddy and turbulent motions in water.

A

Statement -1 is true, Statement-2, Statement -2 is correct explanation of statement-1.

B

Statement-1 is true, Statement-2 is true, Statement-2 is not a correct explanantion of Statement-1.

C

Statement-1 is correct, Statement-2 is false.

D

Statement-1 is false, Statement-2 is true.

Text Solution

Verified by Experts

The correct Answer is:
c
In under water communications, sound waves with higher frequency are preferred as they would carry more energy and can travel larger distances without dispersion.
