Photon Energy Using Wavelength

A photon is an elementary particle, the quantum of the electromagnetic field including electromagnetic radiation (such as light) and the force carrier for the electromagnetic force. The energy of a photon depends only on its wavelength.

The energy equals the Planck constant times the speed of light divided by the wavelength.

Formula

QuantityVariable["E", "Energy"] == Quantity[1, "PlanckConstant"*"SpeedOfLight"]/QuantityVariable["λ", "Wavelength"]
