Question

When a sound wave propagates which physical quantity changes in medium?

Answer 1

Answer:

Velocity of sound is directly proportional to the wavelength. Thus, if the velocity of sound doubles when it travels from one medium to another, its wavelength also doubles. The frequency of sound depends upon the source of sound, not the medium of propagation. Hence, it does not change

Answer 2

Explanation:

It is so,that

Velocity of sound is directly proportional to the wavelength. Then if the velocity of sound doubles when it travels from one medium to another, its wavelength also double.Hope this would be helpful.
