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? Please explain all steps.

FREE Expert Solution

Given: 100 photons

Recall that the energy of 1 photon:

E=hv (1)

where:

h = Planck’s constant (6.626 × 10–34 J • s)
v = frequency (in s–1)


Wavelength and frequency of light are connected using the following equation:

λ=cv (2)

where:
c = speed of light (3.0 × 108 m/s)


Therefore, energy can also be expressed as:
