Answer:

22.5/s is the frequency of the wave

Cricetusgo

The frequency of the wave will be "22.5 Hz".

Given:

  • Wavelength, λ = 20 m
  • Speed of light, C = 450 m/s

We know,

→ [tex]Frequency (f) = \frac{C}{\lambda}[/tex]

By substituting the values,

                         [tex]= \frac{450}{20}[/tex]

                         [tex]= 22.5 \ Hz[/tex]

Thus the approach above is right.
