Ray Optics
Ray optics, or geometrical optics, is the branch of physics that describes light propagation in terms of rays that travel in straight paths and bend at interfaces according to the laws of reflection and refraction.
Importance in UPSCUPSC में महत्व
Frequently tested in UPSC Prelims (GS-1 Science & Tech) through conceptual applications like total internal reflection (mirages, optical fibers), lens makers formula, optical instruments (microscopes, telescopes), and atmospheric phenomena.
