Conversion

Radio frequency to wavelength and vice versa

Electromagnetic waves = Radio waves

The speed of light in free space (a vacuum) is the speed at which electromagnetic waves propagate.

 To use the calculator, simply enter a value. The calculator works in both directions of the ↔ sign.

 Radio frequency f   Hz ↔ Wavelength λ   m f = c / λ λ = c / f Speed of light c = 299,792,458 m/s

Formulas and equations: c = λ · f         λ = c / f = c · T         f = c / λ

 When rounding the speed of light to 300,000,000 m/s you get:

 Frequency Wavelength 1 MHz =       1,000,000 Hz = 106 Hz 300 m 10 MHz =     10,000,000 Hz = 107 Hz 30 m 100 MHz =   100,000,000 Hz = 108 Hz 3 m 1000 MHz = 1000,000,000 Hz = 109 Hz 0.3 m

 Conversion Chart Frequency to Wavelength Radio waves and light waves in a vacuum

There are four parts to a wave:
wavelength, period, frequency, and amplitude
