1. Write some merits of optical fiber.
answer:
1. Better bandwidth.
2. Higher bandwidth means faster speed.
3. Longer transmission distances.
4. Greater flexibility.
5. Improved latency.
6. Stronger security.
2. A diamond ring is placed in a container full of water. Find the critical angle the refractive index of water is given to be 1.32. The refractive index of diamond is 2.45.
answer:
ringμwater = μ water / μ ring = (sin ic ) / (sin r)
=1.32/2.45=sin ic / sin 90
ic =sin-1 (1.32/2.45)
ic=32.60°
