How to Figure the Energy of One Mole of a
Photon
Light is a unique form of energy in that it displays properties of both
particles and waves
...
More specifically, photons are wave
packets that contain a certain wavelength and frequency according to the
type of light
...
Therefore, you can calculate the energy of one mole of photons from either
the light's wavelength or frequency
...
Identify Wavelength in Meters
Identify the wavelength or frequency of the beam of light
...
Note that it is easy to convert between frequency and
wavelength using the equation, the speed of light, c, equals the frequency
times the wavelength
...
Thus, 500 nm is equal to 5
...
2
...
The energy
of a photon is equal to the product of the speed of light, or 3
...
63 x 10 -34, divided by the wavelength
...
9 x 10-19 Joules
...
Multiply by Avogadro's Number
Multiply the photon energy value by Avogadro’s number to find the energy
of one mole of photons
