Photo-electric effect can be explained if light is considered to have:
Correct answer: B. Particle nature
- A. Wave nature
- B. Particle nature
- C. Dual nature
- D. None of these
Explanation
The correct answer is Option B: Particle nature. The photo-electric effect involves the ejection of electrons from a material when exposed to light. This phenomenon is best explained by considering light as particles (photons) that transfer their energy to electrons, causing them to be emitted from the material. The wave nature of light cannot account for the individual interactions between photons and electrons in this process. Options A, C, and D are incorrect because they do not fully address the specific characteristics of light required to explain the photo-electric effect.

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.
