Question

Which statement regarding the relative energies of

monochromatic light with λ = 800 nm and

monochromatic light with λ = 400 nm is correct?

(A) 800 nm light has half as much energy per mole of

photons as 400 nm light.

(B) 800 nm light has the same energy per mole of

photons as 400 nm light.

(C) 800 nm light has twice as much energy per mole of

photons as 400 nm light.

(D) No conclusion may be drawn regarding the relative

energy per mole of photons without knowing the

intensity of the light
