Question

The velocity of sound is not affected by change in

• A. temperature
• B. medium
• C. pressure
• D. wavelength

Answer 1

The correct option is C pressure

Velocity, $v=\sqrt{\frac{VRT}{M}}=\nu \lambda$

$\therefore$ $v$ depends on $V\to medium$, $\lambda \to wavelength$ $andT\to Temparature$

$P{V}^r=$ constant

With change in $P,V$ changes but velocity remains same.
