Question

the frequency of the sound wave is 500 hertz and speed of sound is 125 metre per second then find the wavelength of the sound wave​

Answer 1

Since, medium does not change, the temperature of the medium does not change, pressure does not change, the velocity of sound should remain unchanged and will remain V.

When frequency of the sound wave changes from 300Hz to 150Hz,

The wavelength of the sound wave will double from it's original value when frequency was 300Hz, and velocity of sound shall be still V as before.

Hence,

option V is correct answer.

Answer 2

Answer:

0.25m

Explanation:

As we know that ,

velocity=frequency × wavelength

125=500 × wavelength

wavelength =0.25m
