A wave has a frequency of 46 Hz and a wavelength of 1.7 meters. What is the speed of this wave?

A wave has a frequency of 46 Hz and a wavelength of 1.7 meters than the speed of this wave is 78.2 m/sec.

Given :

Wavelength = 1.7 m

Frequency = 46 Hz

Solution :

We know that the frequency is,

  --- (1)

where,

v is the speed of the wave, w is the wavelength and f is frequency.

Now put the values of w and f in equation (1) we get:

A wave has a frequency of 46 Hz and a wavelength of 1.7 meters than the speed of this wave is 78.2 m/sec.
