Modern view about nature of light is that light behaves as

Correct answer: C. Both waves and particles

  • A. Waves only
  • B. Particles only
  • C. Both waves and particles
  • D. None of these

Explanation

The correct answer is that light behaves as both waves and particles. This is known as wave-particle duality, a fundamental concept in quantum mechanics. Light shows wave-like behavior in experiments involving interference and diffraction, while it exhibits particle-like properties, such as in the photoelectric effect, where light is absorbed in discrete units called photons. The options 'Waves only' and 'Particles only' are incorrect because they do not encompass the dual nature of light. 'None of these' is incorrect as the dual nature is a key aspect of light's behavior.

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.
