Does the beam contain more red-light photons or more blue-light photons? a. The beam contains the same number of red-light photons and blue-light photons, since the energy in the corresponding spectra is distributed equally.
b. The beam contains a greater number of blue-light photons, since they are less energetic relative to red-light photons so that more blue-light photons are needed to correspond to the total energy of red-light photons.
c. The beam contains a greater number of red-light photons, since they are less energetic relative to blue-light photons so that more red-light photons are needed to correspond to the total energy of blue-light photons.
