• 2 − Radio waves and light waves in a vacuum

Conversion: frequency f → wavelength λ and wavelength → frequency

c is the speed of light waves and the speed of radio waves in a vacuum

If instead of the speed of sound in air c = 343 m/s,
the speed of light c = 299792458 m/s is used, the following conversions apply.

Wavelengh Frequency Medium - sengpielaudio

Radio-frequency and microwave radiation are both forms of energy called electromagnetic radiation. Sunshine contains three other forms of electromagnetic radiation: ultraviolet rays, infrared (heat) waves, and visible light waves. These electromagnetic waves spread in a vacuum at the speed of light ≈ 300,000 km/s.

The velocity of propagation of electric signals via cables is nearly 2/3 of the speed of light, that means ≈ 200,000 km/s. The s means seconds.

Sound is also shown at the spectrum chart, but it is no electromagnetic radiation. Sound pressure is the deviation from the local ambient pressure caused by a sound wave - mainly in air. The speed of sound is 343 m/s at 20°C in air.

The notation "eV" stands for electron-volts, a common unit of energy measure in atomic physics.
A graphical representation of the electromagnetic spectrum is shown in the figure below.

Electromagnetic spectrum

Thus we see that visible light and gamma rays and microwaves are really the same
things. They are all electromagnetic radiation; they just differ in their wavelengths.


Sometimes the unit Ångström (angstrom) = 10-10 m = 0,1 nm is used for wavelength.
