In Figure, a light ray is incident at angle theta_(1)= 55^(@) on a series of five transparent layers with parallel boundaries. For layers 1 and 3. L_(1) = 20 mu m, L_(3) = 25 mu m, n_(1) = 1.6, and n_(3) = 1.15. (a) At what angle does the light emerge back into air at the riglit? (b) How much time does the light take to travel through layer 3? |
| Answer» SOLUTION :(a) `55^(@)` (same as incident ANGLE), (b) `1.4 XX 10^(-13)` s | |
