What is the relationship between frequency and wavelength?

Explanation:
Frequency and wavelength are tied together by how fast the wave moves. The relation v = f λ means the speed of the wave equals its frequency times its wavelength. In a given medium, that speed is fixed, so if you raise the frequency, the wavelength must get shorter, and if you lower the frequency, the wavelength gets longer. For electromagnetic waves, in vacuum that speed is the speed of light, so f λ = c. That makes their relationship inverse: doubling frequency halves the wavelength. For example, a 100 MHz radio wave has a wavelength about 3 meters, while a 3 GHz wave has a wavelength about 0.1 meters.
