According to Huygens's theory, light travels in the form of:
Correct answer: C. Wave front
- A. Proton
- B. Corpuscles
- C. Wave front
- D. Electron
Explanation
The correct option is (c). According to Huygens's wave theory of light, light travels in the form of wave fronts, where each point on a wave front acts as a source of secondary wavelets, which propagate forward as spherical waves.

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.
