Question

When sound enters from one medium to
another, then velocity remains same:​

Answer 1

Answer:

thats false, the speed changes so velocity changes unless refractive index of 2 mediums are same

Explanation:

Answer 2

Explanation:

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.
