Physics - Formulas - Frequency and Wavelength

Ever wonder how much energy a photon of light carries? Probably not, but we have some equations to show you anyway!

By using Planck's Constant (which is a value that describes a quanta - or the smallest measurable unit) in relation to frequency and wavelength, we have the two following equations:

and

Note that these equations are used to solve the value of energy in only 1 photon.
