A beam of light traveling through a liquid (of index of
refraction n1 = 1.41) is incident on a
surface at an angle of θ1 = 48° with respect to the normal to
the surface. It passes into the
second medium and refracts at an angle of θ2 = 65° with respect
to the normal.
a. What is the index of refraction of the second material?
b. What is the light's velocity in medium 1, in meters per
second?
c. What is the light's velocity in medium 2, in meters per
second?
