A laser beam is incident at 30° with respect to the normal on a stack of five transparent plates made of materials with the following indexes of refraction (from the top of the stack to the bottom): ni = 1.20, n2 = 1.30, ng = 1.40, n4 = 1.50, ng = 1.60. The plates touch each other. Determine the angle between the outgoing beam and the normal to the last plate. Assume the first and the last plate are in contact with air. (Hint: Before you start calculating, write the expession for the final angle and see if you can simplify it.) Express your answer in degrees.

A light ray travels from vacuum into a slab of material with index of refraction n1 at incident angle θ with respect to the surface.

As the light exits the second slab, what can be said of the final angle ϕ that the outgoing light makes with the normal? (a) ϕ > θ (b) ϕ < θ (c) ϕ = θ (d) The angle depends on the magnitudes of n1 and n2. (e) The angle depends on the wavelength of the light.
