# Wavelength

Written by Jerry Ratzlaff on . Posted in Electrical Engineering

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

## Wavelength formulas

$$\large{ \lambda = \frac { v_w } { f } }$$

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

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

Symbol English Metric
$$\large{ \lambda }$$  (Greek symbol \lambda) = wavelength $$\large{ft}$$ $$\large{m}$$
$$\large{ f }$$ = frequency $$\large{Hz}$$ $$\large{Hz}$$
$$\large{ c }$$ = speed of light $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{sec}}$$
$$\large{ T }$$ = time period, the time required for one cycle or wave occillation $$\large{sec}$$ $$\large{s}$$
$$\large{ v_w }$$ = wavelength velocity $$\large{\frac{ft}{sec}}$$ $$\large{\frac{m}{sec}}$$
