Concept:

Problem: Consider a single photon with a wavelength of λ, a frequency of ν, and an energy of E. What is the wavelength, frequency, and energy of a pulse of light containing 100 of these photons? Hint: Consider which properties can be expressed \"per mole\" of photons. For example, frequency is measured in hertz; have you ever heard of Hz/mol?

E = hvv = Ehc =λ · νv =cλ 

For 1 photon

wavelength = λ

frequency = ν

Energy = E (kJ/mol)
