u=speed, w=wavelenght, f=frequency
It's known that u=w*f =>  f=u/w
                                        u=20m/s     ==>  f=20/0,5  => f=40 Hz
                                        w=0,50m

The frequency of the wave is 40 Hz.

To calculate the frequency of the wave, we use the formula below.

Formula:

  • f = v/λ................... Equation 1

Where:

  • f = Frequency of the wave
  • v = Speed of the wave
  • λ = wavelength of the wave.

From the question,

Given:

  • v = 20 m/s m
  • λ = 0.50 m

Substitute these values into equation 1

  • f = 20/0.5
  • f = 40 Hz.

Hence, the frequency of the wave is 40 Hz.
