3. [5/5 Points] DETAILS PREVIOUS ANSWERS SERPSE10 34.7.OP.020.CTX. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER You are working in an optical research laboratory. One of the pieces of experimental apparatus involves a beam of light entering a transparent rod (see the figure below) of diameter $d = 3.00 \text{µm}$ and index of refraction $n = 1.34$, surrounded by air. Your supervisor has given you the task of determining the cone of acceptance for the rod, which is the maximum angle $\theta_{\text{max}}$ (in degrees) for which the light rays incident on the end of the rod are subject to total internal reflection along the walls of the rod. 63.14
