Fill in the blank: The greater the frequency of a photon, the the energy of the photon.
A wave of red light and a wave of blue light both consist of photons. All the photons in the red light have the same frequency as each other, and all the photons in the blue light have the same frequency as each other. The number of photons in each light wave is the same. In which of the following ways do the energies of the light waves compare?
Which has the greater frequency, a photon of red light or a photon of blue light?
