Question

The velocity of sound in any gas depends upon

• A. wavelength of sound only
• B. density and elasticity of gas
• C. intensity of sound waves only
• D. amplitude and frequency of sound

Answer 1

Answer: (B)

density and elasticity of gas

Answer 2

Velocity of sound in any gas depends upon density and elasticity of gas. $v=\sqrt{\frac{\gamma P}{\rho}}$ or $\sqrt{\frac{B}{\rho}}$
