The material used to obtain plane-polarized light are called:
Correct answer: A. Dichroic substance
- A. Dichroic substance
- B. Solids
- C. Semiconductor
- D. All
Explanation
The correct option is A because Dichroic substances are materials that selectively transmit light waves vibrating in one plane while absorbing or reflecting those vibrating in other planes. They are commonly used to obtain plane-polarized light by selectively filtering out unwanted light vibrations.

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.
