Which statement regarding the relative energies of monochromatic light with λ = 800nm and monochromatic light with λ = 400nm is correct?

Question

Answer

No conclusion may be drawn regarding energy per mole of photons without knowing the intensity of the light.

Answer

800nm light has twice as much energy per mole of photons as 400nm light

Answer

800nm light has half as much energy per mole of photons as 400nm light

Answer

800nm light has the same energy per mole of photons as 400 nm light
