Question

A light ray in the core $(n=1.40)$ of a cylindrical optical fiber is incident on the cladding. See the figure with Problem $14 .$ A ray is transmitted through the cladding $(n=1.20)$ and into the air. The emerging ray makes an angle $\theta_{2}=5.00^{\circ}$ with the outside surface of the cladding. What angle $\theta_{1}$ did the rav in the core make with the axis?

Step 1

4 \sin(\theta_1) = 1.2 \sin(5^\circ) \] \[ \sin(\theta_1) = \frac{1.2}{1.4} \sin(5^\circ) \] \[ \theta_1 = \sin^{-1}\left(\frac{1.2}{1.4} \sin(5^\circ)\right) \] ** Show more…
