Figure P.4.77 depicts a ray being multiply reflected by a transparent dielectric plate (the amplitudes of the resulting fragments arc indicated). As in Section 4.5, we use the primed coefficient notation because the angles are related by Snell's Law.

(a) Finish labeling the amplitudes of the last four rays.

(b) Show, using the Fresnel Equations, that
