Wave nature of light is proved by:
Correct answer: A. Polarisation
- A. Polarisation
- B. Black body radiation
- C. Compton's effect
- D. Photoelectric effect
Explanation
'Polarisation' is the only process which indicates that light is a transverse wave. Polarisation is the feature of wave oscillations having a definite direction proportional to the wave's propagation route. The direction of polarisation is considered to be the direction parallel to the electric field of the EM wave. As light is passed through a polarising screen, the oscillations would be reflected in all directions except one.

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.
