  2. Working of optical fibers
  3. Blue color of the sky
  4. Magnification by a lens

Correct answer and explanation

Correct answer: Working of optical fibers

Explanation: āœ… Correct Answer: B) Working of optical fibers šŸ“š Explanation: Total Internal Reflection (TIR) occurs when light travels from a denser medium to a rarer medium at an angle greater than the critical angle. In optical fibers, light pulses are reflected continuously along the core, allowing for high-speed data transmission over long distances without significant loss. This phenomenon is also responsible for the brilliance of diamonds and the appearance of mirages in deserts.
