Wavelength vs Frequency
EM Wavelength
All electromagnetic waves travel at the speed of light in vacuum.
Formula
lambda = c / f
where c = 299,792,458 m/s. This applies to radio waves, microwaves, infrared, visible light, UV, X-rays, and gamma rays.
Example Calculation
An FM radio station broadcasting at 100 MHz.
- 01lambda = c / f
- 02lambda = 299792458 / 100000000
- 03lambda = 2.998 m
