Question

A longitudinal wave whose wave length is 20cm, propagates
in air at a velocity of 1330m/s Calculate the frequency of
waves​

Answer 1

Given:

Wavelength = 20 cm = 0.2 m

Velocity = 1330 m/s

We know that:

Velocity = Wavelength × Frequency

That is:

$\boxed{\sf{Frequency = \frac{Velocity}{Wavelength}}}$

Substituting the above values in this formula, we get:

$\implies$ f = 1330/0.2

$\implies$ f = 6650 Hz

Therefore:

The frequency of waves: 6650 Hz
