Question

How does the amount of energy in light change as the wavelength increases

Answer 1

Answer

we know,

$E= \dfrac{hc}{\lambda}$

where

E = energy  

h = planks constant

λ = wavelength

from the above equation, we can see that energy is inversely proportional to wavelength.

$E\ \alpha\ \dfrac{1}{\lambda}$

that is why  

Violet color light has low wavelength but the energy of  Violet light is very high whereas red light has low energy and high wavelength.
