Question

A sound wave has a frequency of 1930 Hertz. All sound waves in air travel at 323 m/s. Find the wavelength of the sound wave

Answer 1

0.167 m

Step-by-step explanation:

By the definition of the velocity if a wave ,

The velocity of light, v, is the product of its wavelength, λ , and its frequency, f.

V= fλ

frequency - number of occurances in a unit time

Wavelength - distance between corresponding points of two consecutive waves

(check the graph for wavelength)

`velocity=frequency*wave.length\\wave.length=(velocity)/(frequency)\\ =(323)/(1930)\\ =0.167m`
