Question:

Which one of the following statements is true if the intensity of a light beam is increased while its frequency is kept the same?

A.The photons gain higher speeds.

B.The energy of the photons is increased.

C.The number of photons per unit of time is increased.

D.The wavelength of the light is increased.

Photons:

Photons are tiny packets (also called quanta) of energy associated with electromagnetic radiation. Photons have no mass and no charge. The energy associated with a photon is, {eq}E=h\nu {/eq}, where {eq}h {/eq} is the Planck's constant and {eq}\nu {/eq} is the frequency of the radiation.
