A single optical coating reduces reflection to zero for λ = 550 nm. By what factor is the intensity reduced by the coating for λ = 430 nm and λ = 670 nm as compared to no coating? Assume normal incidence.

A magnifier has a magnification of 5x. How far from the lens should an object be held so that its is seen at the near-point distance of 25 cm? Assume that your eye is immediately behind the lens.

What is the distance, d, between the incoming and outgoing rays?

When you look into your car's 5.0-cm-tall rear-view mirror from 35 cm away, the front of a bus, from the ground to the roof, exactly fills the mirror. If the bus is 17 m from the mirror, how tall is the bus?

The mirror in FIGURE EX34.5 deflects a horizontal laser beam by 60°. What is the angle ϕ?

At what angle ϕ should the laser beam in FIGURE EX34.6 be aimed at the mirrored ceiling in order to hit the midpoint of the far wall?

Two polarizers are oriented at 44.0° to one another. Light polarized at a 22.0° angle to each polarizer passes through both. What is the transmitted intensity (%)?
