Question

The wavelength of a sound wave changes from 5 m to 10 m. How the speed of sound varies?

Answer 1

Answer:

Given:

Wavelength of sound changes from 5 m to 10 m

To find out:

How does the speed of sound varies

Solution:

If is frequency is wavelength and is speed of sound

Then, the relation between these is

Now, if the wavelength of sound wave changes from 5m to 10 m then it means that the wavelength is doubled

Therefore, according to the above relation, for a constant frequency, the speed of sound will also be doubled.
