Explain when the incident ray is parallel to emergent ray?
Asked by | 05 Jun, 2009, 10:27: PM
Expert Answer
Actually the incident ray overlaps with emergent ray in the above case.
For the first surface:
sin0=μsin0 ...(1)
then on the second surfacewe have:
μsin0=sinr' ...(2)
Hence both incident and emergent rays are parallel.
