Question

Change in temperature of the medium changes:

• A. frequency of sound waves
• B. amplitude of sound waves
• C. wavelength of sound waves.
• D. loudness of sound waves

Answer 1

Answer: (C)

wavelength of sound waves.

Change in temperature of the medium changes the velocity of sound waves and hence the wavelength of sound waves. This is because frequency $(\upsilon =\frac{\nu }{\lambda })$ is fixed.
