Change in temperature of the medium changes

Options

A. frequency of sound waves
B. amplitude of sound waves
C. wavelength of sound waves
D. loundness of sound waves

Answer

C

Explanation

Since `upsilon prop sqrt(T)`, therefore, as temperature of the medium change, `upsilon` also changes. Also `upsilon = v lambda`. (v of the medium always remains constant). So, with the change in temperature, wavelength of sound wave changes. The correct option is (c).
