Question
Suppose the prism of Fig. 33-34 has apex angle $\phi=60.0^{\circ}$ and index of refraction $n=1.56$. (a) What is the smallest angle of incidence $\theta$ for which a ray can enter the left face of the prism and exit the right face? (b) What angle of incidence $\theta$ is required for the ray to exit the prism with an identical angle $\theta$ for its refraction, as it does in Fig. 33-53?
Step 1
For the first interface, we have \[\theta_{r1} = \sin^{-1}\left(\frac{\sin\theta}{n}\right)\] and for the second interface, we have \[\theta_{r2} = \sin^{-1}\left(\frac{\sin\theta_r}{n}\right)\] Show more…
