how is wavelength related to the energy of the colors of light?
Answers
Relation of wavelength to the energy of the colors of light
Explanation:
Humans see visible light as white, but it truly comes in seven colors of the rainbow. The visible light spectrum has seven colors, with violet and blue having shorter wavelengths and having high energy. At the other side of the spectrum, toward red have longer wavelength and results in lower energy.
Mathematical expression is :
c = ν/λ
ν - frequency
λ - wavelength
c - speed of light
Then it can be rearranged as
ν = c/λ
According to Planck's equation:
Energy = h × c/λ
= h × ν
h - Planck's constant
It is clear that if frequency increases, wavelength decreases and results in increase in energy.
