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

Answer

we know,

where

E = energy  

h = planks constant

λ = wavelength

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

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.

no

sodium is solid at rt
