Wavelength equals the velocity of the wave divided by the frequency; for an EM wave, the velocity is the speed of light. So the wavelength of this wave is 299792458/1.9 x 106 = 157.78550421... ~ 158 metres or 173 yards.

One convenient working definition of 'radio' is: Electromagnetic radiation withfrequency up to 300 GHz / wavelength down to 1 millimeter.'Radio' is our name for the lowest frequency / longest wavelength, so there'sno lower limit on frequency, or upper limit on wavelength.
speed of light = wavelength * frequence speed of light = 3*10 8th power
Radio waves are the lowest frequency (and therefore longest wavelength) waves in the electromagnetic spectrum.
The wavelength is greater than 300E6/300E9 = 1 mm and the frequency is less than about 300 Gigacycles.
Radio communication works on radio signals that are "beamed" into the air on a certain frequency. Frequency is a certain wavelength or band. The receiving equipment has to be set to receive the signal on the same frequency.

Frequency = speed/wavelength = 300,000,000/3 = 100 MHz.
Frequency = speed/wavelength = 300,000,000/150 = 2 MHz
Frequency = speed/wavelength = 300,000,000/3 = 100 MHz.
Speed, wavelength and frequency.

The energy of EM radiation depends on its frequency, and the lowest frequency corresponds to the lowest energy. Radio waves are at the low end of the energy and frequency spectrum.
