The polarization of light by tourmaline crystals is due to the _effect.
Correct answer: D. Selective absorption
- A. Selective diffraction
- B. Selective reflection
- C. Selective interference
- D. Selective absorption
Explanation
Polarized light can also be produced by using a tourmaline crystal. Tourmaline (a double-refracting substance) removes one of the polarized rays by selective absorption. Organic substances that affect polarized light that passes through their solution are called optically active.

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.
