Refraction Example A light ray starts in a
medium with index of refraction n1 and goes into
a medium with index of refraction n2. The angle
of incidence is q1. The angle of refraction
(transmission) is q2. a) If n1 lt n2, where is
the light ray traveling fastest? b) If n1 lt n2,
which is larger, q1 or q2? c) A beam of light
is incident on the interface between plastic (n
1.3) and air with a 40o angle as shown. What is
the angle of the refracted ray?
