Wavelength

Written by Jerry Ratzlaff on . Posted in Electrical Engineering

wavelengthWavelength, 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 \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{sec}}\)
