  • Change in temperature of the medium changes (a) frequency of sound waves

Change in temperature of the medium changes
(a) frequency of sound waves.
(b) the amplitude of sound waves.
(c) the wavelength of sound waves.
(d) the loudness of sound waves.

Answers (1)

The answer is the option (c) 

Thus, on increasing temperature, the speed also increases, as frequency remains constant during the propagation of the wave. Since v=u\lambda, the wavelength also increases with velocity.
