Huygen's principle is used to show that _:
Correct answer: C. All points on primary wave front are source of secondary wavelet
- A. Light travels in straight line
- B. Light has dual nature
- C. All points on primary wave front are source of secondary wavelet
- D. None of these
Explanation
Huygens principle enables us to determine the position and shape of a new wavefront by considering each point on the primary wavefront as a source of secondary wavelet. This principle helps in understanding wave propagation and interference phenomena. The other options are incorrect because they do not directly relate to Huygen's principle and the behavior of wavefronts.

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.
