Question

If at a place the speed of a sound wave of frequency 300Hz is V, the speed of another wave frequency 150Hz at the same place will be:
1)V. 2)V/2. 3)2V. 4)4V


Answer it plss... Step by step​

Answer 1

Explanation:

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.
