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.
