The equation that describes the relationship between the energy of light and wavelength is the following:

E = hc/λ

Where:

E = Energy of light (in Joules)
h = Planck’s constant (6.62 x 10-34 m2 kg / s)
c = Speed of light in a vacuum (3.00 x 10^8 m/s)
λ = Wavelength of light (in meters)

This equation shows that the energy of light is inversely proportional to its wavelength. This means that as the wavelength of light increases, the energy of light decreases.
