Formule

## 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.

Exemple Résolu

An FM radio station broadcasting at 100 MHz.

  1. 01lambda = c / f
  2. 02lambda = 299792458 / 100000000
  3. 03lambda = 2.998 m
