In all of the following, polarization of light is used EXCEPT
Correct answer: B. for calculating the fringe spacing
- A. in curtain-less windows
- B. for calculating the fringe spacing
- C. for finding concentration of sugar in blood
- D. for controlling the head light glares in night driving
Explanation
Polarization of light refers to the alignment of the electric field vectors of light waves in a particular direction. It is a phenomenon that occurs when light waves pass through certain materials or undergo specific interactions.Calculating the fringe spacing typically refers to interference patterns, such as those observed in Young's double-slit experiment. Polarization is not directly involved in determining the fringe spacing in interference patterns.

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.
