Question

You are only given the average energy of 392.2kj/mole photons. And I need to figure out what the wavelength is. how do I go about finding that?

Answer 1

Answer #1

ANSWER;

Enery E = hv

h = planks constant,

v = frequency = vlocity of light / wavelength

Energy per mole of photon = 39220J

Energy per photon = 39220 / Avagadroes no.

39220 / 6.02 X 10²³ = 6.62 X 0^-34 X 3 X 10⁸/wavelength

wavelength = 6.62 X 0^-34 X 6.02 X 10²³ X3 X 10⁸ / 39220 = 3.04 X10^-6 m

The energy of a mole of photons of light in the electromagnetic spectrum decreases logarithmically as a function of increasing wavelength. In the visible range, light has between 40 and 80 kcal/mole of photon energy. Below about 400 nm wavelength, the energy increases significantly.
