A mixture of red and violet light is incident on a glass-air interface. The indices of refraction for red and violet light in glass are n(red)=1.52 and n(violet)=1.538. What color of light enters the air? http://www.webassign.net/cj8/q_10.gif attempt to solve: I found that the critical angle for the violet light is 40.56 degrees and 41.14 degrees for the red. If the critical angle for the red light is larger, shouldn't there be total internal reflection? Thanks in advance!!
