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.
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.

Wavelength = speed/frequency = 300,000,000/100,000,000 = 3 meters
The frequency of a radio wave with a wavelength of 3m can be calculated using the formula: frequency = speed of light / wavelength. The speed of light in a vacuum is approximately 3 x 10^8 meters per second. Therefore, the frequency of the radio wave would be 3 x 10^8 / 3 = 1 x 10^8 hertz.
To find the frequency of a wave, you can use the equation: frequency (f) = speed of the wave (v) / wavelength (λ). If the wavelength is 3m and you know the speed of the wave (for example, in air at room temperature it is about 343 m/s), you can calculate the frequency using this equation.
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 velocity of a wave is wavelength x frequency. velocity = 3m x 12/s = 36m/s
The frequency of a wave can be calculated using the formula: frequency = wave speed / wavelength. Plugging in the values given, we get: frequency = 24 m/s / 3 m = 8 Hz.
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.
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.
Speed, wavelength and frequency.
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.
