According to Huygen's principle, light travels in the form ofI. photonsII. corpusclesIII. wavefronts
Correct answer: B. III only.
- A. I only.
- B. III only.
- C. I and II.
- D. II and III.
Explanation
Huygen's principle states that every point on a wavefront is a source of wavelets, which spread forward at the same speed. This principle models light as traveling in the form of wavefronts. Therefore, Option B: III only is correct. Options involving photons (Option A and C) are incorrect because they relate to the particle nature of light, which is described by quantum theory, not Huygen's principle. Option D is also incorrect because it includes corpuscles, which is a concept from Newton's corpuscular theory of light, not Huygen's wave theory.

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.
