# Wavelength

Written by Jerry Ratzlaff on . Posted in Electromagnetism

Each wave has a shape and length.  Wavelength, abbreviated as $$\lambda$$ (Greek symbol \lambda), is the distance between the crests of a wave.

## Wavelength formulas

 $$\large{ \lambda = \frac { c } { f } }$$ $$\large{ \lambda = c \; T }$$

### Where:

$$\large{ \lambda }$$  (Greek symbol \lambda) = wavelength

$$\large{ f }$$ = frequency

$$\large{ c }$$ = speed of light

$$\large{ T }$$ = time period, the time required for one cycle or wave occillation

### Solve for:

 $$\large{ c = \frac { \lambda } { f } }$$ $$\large{ T = \frac { 1 } { f } }$$
