Which of the following properties proves that light behaves as particles? I. Polarization II. Photo electric effect III. Compton effect IV. Diffraction
Correct answer: B. II and III are correct
- A. I and II are correct
- B. II and III are correct
- C. III and IV are correct
- D. I and IV are correct
Explanation
The photoelectric effect and the Compton effect provide clear evidence for quantised photons and particle-like interactions of light with electrons; polarization and diffraction are wave phenomena.

About Optics
Light is studied through reflection, refraction, dispersion, interference, diffraction and polarization, linking ray behavior with its wave nature. Questions may involve mirrors, lenses, optical instruments, refractive index and image formation, while geometrical optics deals with rays and wave optics explains effects such as interference and diffraction.
