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 its the photon frequency ($\nu$), and there is a direct relationship between this frequency and the photon energy ($\epsilon$):
 $ \epsilon = h \nu $ |
$E$
Photon energy
$J$
5141
$\nu$
Photon frequency
$Hz$
5564
$h$
Planck constant
6.62607004e-34
$J s$
5142
where the planck constant ($h$) has a value of $6.62\times 10^{-34} , \text{Js}$.
