Huygen's principle is used to
Correct answer: D. all
- A. Locate wavefront
- B. Explain diffraction
- C. Determine speed of light
- D. all
Explanation
The correct option is D because Huygen's principle is a fundamental concept in wave optics. It is used to locate wavefronts, explain diffraction phenomena, and understand the propagation of 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.
