Wavelength

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

Wavelength formula

(Eq. 1)  \(\large{ \lambda = \frac { c } { f }    }\)

(Eq. 2)  \(\large{ \lambda =  c \; T    }\)

Where:

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

\(\large{ f }\) = frequency

\(\large{ c }\) = speed of light or velocity

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

Solve for:

\(\large{ c = \frac { \lambda } { f }    }\)

\(\large{ T = \frac { 1 } { f }    }\)
