Question

Change in temperature of medium changes the

• A. frequency of sound wave
• B. amplitude of sound wave
• C. waveform of sound wave
• D. wavelength of sound wave

Answer 1

The correct option is D wavelength of sound wave

$v=\sqrt{\frac{\gamma RT}{M}}$, as $T\uparrow$ $v\uparrow$

But $\lambda =\frac{v}{x}$, as $v\uparrow$ $\lambda \uparrow$
