D)the frequency of the photons.

Question

Quizplus · Accepted Answer

Increasing the brightness of a beam of light, according to Einstein's photoelectric effect theory, increases the number of photons in the beam without affecting the energy of each photon, the speed of the photons (which is constant at the speed of light in vacuum), or the frequency of the photons (which is determined by the color or wavelength of the light).
