Polarisation of light shows that light is:
Correct answer: D. Transverse waves
- A. Corpuscular in nature
- B. Of extremely short waves
- C. Longitudinal waves
- D. Transverse waves
Explanation
Polarisation of light refers to the orientation of the oscillations of light waves. When light is polarised, its waves vibrate in a particular plane. The correct answer is 'Transverse waves' because light waves are transverse in nature, meaning they oscillate perpendicular to the direction of wave propagation. The other options are incorrect as they do not accurately describe the nature of light waves or the concept of polarisation.

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.
