Total Internal Reflection (TIR)
TIR is an optical phenomenon occurring when a light ray traveling from a denser medium to a rarer medium strikes the interface at an angle greater than the 'critical angle', resulting in the light being completely reflected back into the denser medium.
Importance in UPSCUPSC में महत्व
TIR is a high-frequency topic in UPSC Prelims (Science & Tech) due to its direct application in fiber optics, telecommunications, and natural phenomena like mirages.
