If two photons interact in the same direction what will change:

Correct answer: C. Intensity

  • A. Mass
  • B. Energy
  • C. Intensity
  • D. None of these

Explanation

When two photons interact in the same direction, the intensity of the resulting light may change. Intensity refers to the amount of energy per unit area per unit of time carried by the photons. The interaction of the photons may lead to constructive or destructive interference, affecting the overall intensity of the light in that direction.

About Dawn of Modern Physics

Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
