-
5.The critical angle for the glass of an equiangular prism ABC is 60°. A ray of light incident on side AB is refracted along DE, making an angle of 150° with side AC. Given that ∠EDB = 90°, what is the path of the incident ray on AB and the subsequent path of ray DE from point E?
- A.The incident ray is normal to AB, and DE undergoes refraction at E before emerging.
- B.The incident ray is at 30° to AB, and DE undergoes total internal reflection at E.
- C.The incident ray is normal to AB, and DE undergoes total internal reflection at E.
- D.The incident ray is at 60° to AB, and DE undergoes refraction at E without reflection.
