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.

The frequency of a 150 meter radio wavelength can be calculated using the formula: frequency = speed of light / wavelength. For a 150 meter wavelength, the frequency would be approximately 2 MHz (megahertz).
Frequency = speed/wavelength = 300,000,000/3 = 100 MHz.
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.
Speed, wavelength and frequency.
The wavelength of a radio wave can be calculated using the formula: wavelength = speed of light / frequency. For a radio station broadcasting at 3 MW (megawatts), which is likely to be in the medium-frequency range, the approximate wavelength would be around 100 meters.
As you move from gamma rays to radio waves on the electromagnetic spectrum, the wavelength gets longer and the frequency decreases. Gamma rays have the shortest wavelength and highest frequency, while radio waves have the longest wavelength and lowest frequency.
