Cuestions A radio station is transmitting at a frequency of 15.42 MHz. Calculate the frequency of
the transmission

The wavelength of the transmitting waves is 55.35 m

Explanation:

Radio waves are electromagnetic waves, thus travel at the speed of light (3.0 x m/s)

The frequency of transmission = 15.42 MHz

                                                   = 15.42 x Hz

But,

         v = fλ

where: v is the velocity of the wave, f is the frequency and λ is the wavelength

The wavelength of the transmitting waves can be determined by,

λ =

  =

  = 55.3506

λ = 55.35 m

The wavelength of the transmitting waves is 55.35 m.

i think they are all correct

explanation:

they seem good
