The photon model equation relates the frequency and energy of a photon together by a constant of proportionality, where

#E# is the energy of the photon (#J# )#f# is the frequency of the photon (#s^(-1)# )#h# is Plank's constant (#~~6.63*10^(-34)Js# )

The frequency and wavelength of light are also related by the wave equation where

#c# is the speed of light (#~~3.00*10^8ms^(-1)# )#f# is the frequency of the light (#s^(-1)# )#\lamda# is the wavelength of the light (#m# )

By rearranging to get
