Question

A wave of frequency 13000 Hz travels 1300m in 4.0s. What is the wavelength of the wave?

Answer 1

Given : Frequency (n) = 13000 Hz

Distance travelled (d) = 1300 m

Time (t) = 4 sec

To Find : Wavelength (x) = ?

Solution:

Velocity= distance/time

= 1300/4

= 325 m/s

Now

Velocity= nx

325 = 13000 × x

x = 1/40

x = 0.25 m

Wavelength of wave is 0.25 m
