e. What is the wavelength,? 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? 0.01λ, 0.01ν, and 0.01E 0.01λ, ν, and 100E

Answer 1

The wavelength and frequency remain the same while the energy is multiplies by the number of photons

Answer 2

The wave length and frequency of the pulse of light is the same of a single photon.

The energy will be the number of photons times the energy of a photon, i.e. 100e.

By the way, the energy of a photon is the product of the Planck's constant, h, times the frequency. This is not part of the question.
