Question

The speed of sound doubles from 330 m/s to 660m/s going from air to a vibrating tuning fork.

Compare the frequency and wavelength of the wave in these 2 mediums.

Answer 1

Lets learn the relationship

`\\ \rm\dashrightarrow \lambda=(v)/(\\u)`

`\\ \rm\dashrightarrow \\u=(v)/(\lambda)`

`\\ \rm\dashrightarrow \\u\propto \lambda\propto v`

Hence.

frequency and wavelength will be. doubled also
