What is the energy of a photon with a wavelength of 650 nm?

A classroom laser pointer is often red in color, and has a wavelength of 650 nm, and a power of 3 mW. The amount of energy in a single photon at this wavelength is just E = 6.626 x 10-34 J s * 2.998 x 108 m/s / 650 x 10-9 m which is 3 x 10-19 J per photon.

How do you find the energy of a photon?

Calculation Theory
  1. Photon energy can be expressed using any unit of energy such as the electronvolt (eV) or the Joule (J).
