The Energy of Light involves the use of a new variable Planck's Constant.

Light as Particles

Concept #1: The Energy of Light

Concept #2: Photon Energy Formulas

Example #1: Calculate the energy of a photon with a wavelength of 293.7 m.

Concept #3: Moles and Energy

Example #2: Calculate the energy for a mole of photons with a frequency of 4.29 x 1015 s-1.

Practice: Calculate the energy (in nJ) of a photon emitted by a mercury lamp with a frequency of 6.88 x 1014 Hz.

Practice: A light ray has a wavelength that is 835 µm contains 6.32 x 10-3 J of energy. How many photons does this light ray have?

Practice: How much energy (in kJ) do 4.50 moles of photons contain at a wavelength of 705 nm?
