Colors and Photons

Storyboard

Light, in its corpuscular picture, is described by introducing a particle that we call the photon.

Its color is a reflection of its energy being the frequency of this directly proportional to this.

The spectre

Image

As the angle of refraction depends on the frequency or wavelength of light in glass, a prism can be used to decompose light into its different colors.

This results in what we call the spectrum of light.

Photon Energy

Equation

The color of light is associated with the frequency
u of this and that there is a relationship between this frequency and the energy of the photon E:

$ E = h \nu $
