Question

**Please Do Not Forget The Visual Representation. Thank you!!**

Problem Statement Light strikes a 5.0-cm thick sheet of glass at an angle of incidence in air of 50°. The sheet has parallel faces and the glass has an index of refraction 1.50. (a) What is the angle of refraction in the glass? (b) After traveling through the glass the light re-emerges into the air. What is the final angle of refraction in air? (c) As it leaves the glass, by what distance is the path of the ray is displaced from what it was before entering the glass? Visual Representation • Draw a ray diagram • Draw a line normal to the boundary • Show the ray bending in the correct direction • Label angles of incidence and refraction measured from the normal
