The correct answer is option A.
Explanation:
Energy of the photon of an electromagnetic radiation is give by Planck's equation:
Where:
h = Planck's constant
c = speed of light
= Wavelength of the photon's radiation
Energy of photon of 800 nm monochromatic light
Energy per mole of photons:
..[1]
Energy of photon of 400 nm monochromatic light
Energy per mole of photons:
..[2]
[1] ÷ [2]
