Optical active crystals rotates the __________________?
Correct answer: B. polarization plane
- A. vibrating plane
- B. polarization plane
- C. diffraction plane
- D. interference plane
Explanation
An optically active crystal rotates the plane in which a plane-polarized light wave vibrates, called the plane of polarization. Option a may be chosen because the electric field does vibrate in that plane, but the named optical quantity being rotated is the polarization plane.

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.
