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

Answer 2

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