Textbook Question
Chapter 17, Problem 66EAP
Engineers are testing a new thin-film coating whose index of refraction is less than that of glass. They deposit a 560-nm-thick layer on glass, then shine lasers on it. A red laser with a wavelength of 640 nm has no reflection at all, but a violet laser with a wavelength of 400 nm has a maximum reflection. How the coating behaves at other wavelengths is unknown. What is the coating’s index of refraction?

Astronauts placed a mirror on the surface of the Moon to be used for optical measurements of the precise distance to the moon. Visible light is sent from
the Earth and is reflected back from the moon. If the mirror has a diameter of 30 cm, roughly how large is the beam of reflected light that reaches Earth?
The distance from the Earth to the Moon is 3.8×108
meters. You can assume the light from Earth is a plane wave when it strikes the mirror.
A light with a wavelength of 500 nm (red color) travels from a laser to a photocell in 15 ns. When a thin glass slab is placed normally in front of the photocell it takes the light 18 ns to travel from the laser to the photocell? When the Laser beam passes through the glass slab it changes to blue in color (λ = 660 nm). What is the thickness of the glass slab?

what is the resonant frequency (w0) of the fused quartz? (Brute force Hint: you could read off
two points from the curve, solve for w0 and then check your answer with a third point on the
curve). Don't forget that that w=2nf, and f^x=c, and l= wavelength.
Its okay when you pick the third point on the curve you don't get the same w0.

Inside the box at one end is a small radio transmitter that emits radiation with a wavelength of 0.120 m. A receiver is placed at the other end, 7.20 m away. Assume both the transmitter and the receiver are on the floor of the box. The walls and floor of the box interior are treated to minimize reflection of radio waves. The ceiling of the box interior, however, is metal, so the radio waves can reflect off of it almost perfectly. The radio waves can take two paths from the transmitter to the receiver: a straight-line path, and a path that reflects off the ceiling of the box interior. Note that there is a phase shift when the waves reflect off the ceiling.
