Planck’s Equation

Electromagnetic Wave Equation

E=hvE=energy in joulesH=planck’s constant=6.63E-34J*sV=frequency (per second or Hz)

C=λvC=speed of light=3.00E8m/s λ=wavelength in metersV=frequency (per second or Hz)

The energy(E) and the frequency(V) of an electromagnetic wave are directly related.

Frequency and wavelength are inversely related.

Wavelength and energy are inversely related.
