E)depends on both the mass and speed of the photon.

Question

Quizplus · Accepted Answer

The energy of a photon is given by the equation E = hc/λ, where E is the energy, h is Planck's constant, c is the speed of light, and λ is the wavelength. This shows that the energy of a photon is inversely proportional to its wavelength.
