Chapter 9: Problem 12

Just before the Sun sets, a driver encounters sunlight reflecting off the side of a building. Will Polaroid sunglasses stop this glare? Why?

Short Answer

Expert verified
Why or why not? Answer: Yes, Polaroid sunglasses can effectively stop glare caused by sunlight reflecting off the side of a building. This is because they are designed to block horizontally-polarized light, which is the main component of glare in this situation.

Step by step solution

01

Understand how Polaroid sunglasses work

Polaroid sunglasses are designed to block out horizontally-polarized light. This is because glare is mainly horizontally polarized, which means that the oscillations of light waves in glare are primarily in the horizontal direction. By filtering out horizontally-polarized light, Polaroid sunglasses can effectively reduce glare.
02

Determine the polarization of reflected sunlight

When sunlight reflects off a flat, non-metallic surface like a building, it becomes partially polarized. In particular, the horizontal component of light becomes dominant, as the vertical components cancels out due to reflection from the flat surface. This results in horizontally-polarized glare.
03

Assess the effectiveness of Polaroid sunglasses in this situation

Since the glare caused by sunlight reflecting off the building is horizontally polarized, Polaroid sunglasses should be able to stop this glare. The sunglasses will block the horizontally-polarized light and allow only the vertically-polarized light to pass through, reducing the glare that the driver experiences. In conclusion, Polaroid sunglasses will effectively stop the glare caused by sunlight reflecting off the side of a building because they are designed to block horizontally-polarized light, which is the main component of glare in this situation.

Most popular questions from this chapter

A piece of glass is immersed in water. If a light ray enters the glass from the water with an angle of incidence greater than zero, in which direction is the ray bent?

Suppose a \(20-\mathrm{m}\) -long tube is filled with benzene and the ends sealed off with thin disks of glass. If pulses of red and blue light are admitted simultaneously at one end of the tube, will they emerge from the opposite end together, that is, at the same time? If not, which pulse will arrive at the far end of the tube first? Why?

Explain why images seen through flat, smooth, uniform, plate-glass windows are undistorted.

An interference pattern is formed by sending red light through a. pair of narrow slits. If blue light is then used, the spacing of the bright areas (where constructive interference takes place) won't be the same. How will it be different? Why?

Water droplets in clouds scatter sunlight in ways that are similar to those of air molecules. Because clouds are white (during the day), what can you conclude about the frequency dependence of scattering by cloud particles?
