Question

As shown in Figure P22.49, a light ray is incident normal to one face of a $30^{\circ}-60^{\circ}-90^{\circ}$ block of dense flint glass (a prism) that is immersed in water. (a) Determine the exit angle $\theta_{4}$ of the ray, (b) A substance is dissolved in the water to increase the index of refraction. At what value of $n_{2}$ does total internal reflection cease at point $P_{f}$

Step 1

The light ray enters the prism at normal incidence, so it does not refract at the first interface. Show more…
