1) Why are diode lasers superior for launching light into a fibre?
2) Are light-emitting diodes suitable for launching light into single mode fibres/
3) What is the relationship between 2 polarizer angles when the transmitted light intensity is
(a) maximum
(b) zero
?
4) When a polarizer is rotated in front of a light source, what is observed? why?
5) When a second polarizer is inserted, under what circumstance will the transmitted light intensity be zero?
6) When 2 polarizers are facing tghe same direction and looked into, we can see things. but when 1 of the polarizer is changed direction, nothing can be seen through both of them when together. then when another polarizer is put diagonally between the 2 polarizers, things can be see. Explain the paradox here.
