The process of ejection of loosely bound electrons from a certain photo sensitive surface by absorption of photon is called:
Correct answer: B. Photoelectric effect
- A. Compton effect
- B. Photoelectric effect
- C. Pair production
- D. Black body radiation
Explanation
The photoelectric effect refers to the phenomenon where photons are absorbed by a photo-sensitive surface, resulting in the ejection of loosely bound electrons from the surface.

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.
