The wavelength of the radio waves emitted by the radio galaxies which have twin radio jets that emanate from a central core is determined as 15 m.

Wavelength of the radio waves

The wavelength of the radio waves is the distance traveled by the radio waves. The magnitude of the wavelength is determined from the ratio of speed of radio waves to the frequency of the radio waves.

v = fλ

where;

  • v is the speed of the radio waves
  • f is the frequency of the radio waves
  • λ is the wavelength of the radio waves

Radio wave is an example of electromagnetic radiation, and it travels at the same speed as light (3 x 10⁸ m/s).

λ = v/f

λ = (3 x 10⁸ ) / (20 x 10⁶)

λ = 15 m

Thus, the wavelength of the radio waves emitted by the galaxy is 15 m.
