Question

A. What kind of polarization is used in 3-d movie houses?

circular polarization

Political polarization

horizontal polariation

vertical polarization

B. When sunlight reflects off a horizontal surface, such as a street or field, the light so reflected is

horizontally polarized

circularly polarized

randomized and polarization vanishes

vertically polarized

C. The light is sent through 1 polaroid filter and then through another filter that is tilted at an angle of 45 degrees with respect to the first. How much does the intensity of the beam fall as it goes through the second filter?

By zero - none of the beam makes it through

By square of 2

By half

By 4

D. Brewster's angle describes the relationship between an incident beam and the _____________ of the reflected beam.

E. What is the tangent of Brewster's angle?

n2/n1

n2 sin(theta 2)

n1 sin(theta 1)

The projection of the polarization plane on the direction of propagation of the wave

F. Suppose you know that the polarization of a microwave is in the horizontal plane. You have a metal sheet with long narrow gaps in it. In order to use the metal sheet as a polarizing filter and block the microwaves, you need to hold the metal sheet so that the long slits are

can't say without more information

horizontal

vertical

G. According to Malus' Law the intensity of a beam that has been polarized decreases with the angle measured from polarization according to

the cosine-squared of that angle

the cosine of that angle

the sine of that angle

the sine-squared of that angle

H. When Brewster's Law holds, the angle between the refracted beam and the reflected beam is

180 degrees

90 degrees

60 degrees

45 degrees

Answer 1

(1) Circular polarization

(2) Randomly polarized

(3) By half

(4) n2/n1

I can only answer the first four parts as per Chegg's policy. Please post remaining as a separate question.
