The displacement of the beam is expressed as:
Problem 8: A flat slab of material (nm = 2.1) is d = 0.35 m thick. A beam of light in air (na = 1) is incident on the material with an angle θa = 55° with respect to the surface's normal.
Part (a) Numerically, what is the displacement, D, of the beam when it exits the slab?
