A beam of light traveling in air strikes a very smooth water surface in a glass bowl at an angle of incidence of 35 degrees. The water has an index of refraction of 1.33, glass 1.5. Light then refracts through the glass bottom and back into the air.
(a) what is the angle of refraction for the transmitted light into the glass?
(b) Prove that the emergent beam is parallel to the incident beam.
