This equation allows you to calculate wavelength from frequency, and frequency from wavelength.

In this equation:

(lambda) represents wavelength (in metres).

** ****c ** represents the velocity of light (which is approximately 3.00×10^{8} m/s).

** f** represents frequency (in hertz).

Wavelength is the distance between two peeks of the signal.

frequency is the number of oscillations in one second.
