Speed of Waves

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason $\mathbf{R}$

Assertion A: A sound wave has higher speed in solids than gases.

Reason R: Gases have higher value of Bulk modulus than solids.

In the light of the above statements, choose the correct answer from the options given below

Show answer and solution

Answer: (c)

A: true, $v = \sqrt{E/\rho}$ and solids have far larger elastic moduli, so sound is faster in solids.
R: false, gases are highly compressible, so their bulk modulus is much smaller than that of solids.
So the answer is (c) A is true but R is false.
