1

finding refractive index

n = c/v or sin i/sin r (less dense to dense); sin r/sin i (dense to less dense)

2

critical angle, C

sin^-1(1/n)

3

what is a critical angle?

the angle of incidence in an optically denser medium for which the angle of refraction in the optically less dense medium is 90 degrees.

4

advantages of optical fiber

- can carry much more information over long distances.
- immune to electromagnetic interference.
- signal transmitted experiences much lesser signal loss.

5

finding angle of refraction, r

sin^-1(sin i/n)
