Question

A Sound wave travels 60m in the time taken to produce 60 waves. Find the wavelength of the sound wave in centimetres.

Answer 1

v=f x lambda
60=60xlambda
wavelength=1m
In cm....w=100 cm

Answer 2

The wavelength of the sound wave in centimetres is 120.

Explanation:

As we know that one wave is equal to one wavelength so the wavelength of the sound wave.

To find, the wavelength of the sound wave in centimetres = ?

∴  The wavelength of the sound wave in centimetres

=$\dfrac{60\times 100}{50}$

$=60\times 2=120$

= 120

Hence, the wavelength of the sound wave in centimetres is 120.
