Suppose a laser produces green light in stead of the red light obtained from a He-Ne laser. Go to next question. Go back to the beginning. I want to choose another chapter. The energy of a photon is higher when the frequency is higher.
Green light has higher frequency than the red light.
Back to the same question. Go to the next question. Back to the beginning - I want to choose another chapter. We are talking about the individual photons. The energy is associated strictly with the frequency of the photon.
