Light propagates through space as a wave is evident by all of the following EXCEPT:
Correct answer: B. Photoelectric effect
- A. Interference
- B. Photoelectric effect
- C. Diffraction
- D. Polarization
Explanation
The photoelectric effect is a phenomenon in physics where electrons are emitted from a material (usually a metal) when it absorbs light or electromagnetic radiation of sufficient energy. This effect was crucial in the development of quantum mechanics and provided evidence for the particle-like properties of light.

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.
