Question

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

Answer 1

Hey Mate!!

The speed of sound will be doubled..

If f is frequency λ is wavelength and v is speed of sound

Then, the relation between these is

v= f × λ

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.

Hope this helps you!!
