    Light is incident along the normal to face AB of a prism that has a refractive index n and an angle α=30∘, as shown in (Figure 1). When the prism is in air, the light undergoes total internal reflection. However, when the prism is immersed in water, a faint refracted ray emerges at an angle of 70 ∘ to the normal of face AC. The index of refraction of water at this temperature is 1.333. Determine n. Express your answer...

    2. A block of plastic with refractive index np-1.68 is immersed in oil (no-1.516). Randomly polarized light (ie, 50% s-polarization and 50% p-polarization) is incident from the oil towards the plastic at an angle of 65" to the normal. a) What percentage of the p-polarized component of the light is reflected off the plastic? b) What percentage of the total incident power of the light is transmitted into the block? c) What is the ratio of the s-polarized reflected power...
