Which of the following is NOT the application of polarisation of light?
Correct answer: D. Astronomers use lenses in telescopes to magnify images of celestial objects.
- A. Photographers use filters to reduce glare and achieve clearer images.
- B. Drivers use sunglasses to reduce glare from the road and other vehicles.
- C. Fishermen use eyewear to minimize reflections off the water surface.
- D. Astronomers use lenses in telescopes to magnify images of celestial objects.
Explanation
The correct answer is Option B. Polarized sunglasses are designed to reduce glare from reflective surfaces like roads and water, but they are not specifically intended to diminish the brightness of headlights. Option A is incorrect because photographers do use polarized filters to reduce glare. Option C is incorrect because fishermen use polarized lenses to see beyond the surface glare of water. Option D is not related to polarization; astronomers use lenses for magnification, not glare reduction.

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.
