Question

A tuning fork having frequency 250hz emits a wave which has a wavelength of 1.35m find the speed of sound in air

Answer 1

Velocity = f × Wavelength.

So, v = 250×1.35

V= 337.50m/s

Answer 2

Given that,

Frequency of tuning fork, f = 250 Hz

Wavelength emitted by the fork, $\lambda=1.35\ m$

To find,

The speed of sound in air.

Solution,

The speed of a wave in terms of frequency and wavelength is given by :

$v=f\lambda\\\\v=250\ Hz\times 1.35\ m\\\\v=337.5\ m/s$

So, the speed of sound in air 337.5 m/s.
