  • Correct CID or lose 5 points

  • No more than 3 papers stapled neatly to the answer sheet









When unpolarized light of intensity Io is incident on a polarizer what is the intensity of the light that will be transmitted?

  • Io /2

  • Io /4

  • 2Io

  • zero

  • Depends on the angle of the transmission axis of the polarizer


Unpolarized light of intensity I0 is sent through three polarizers, one after the other, which pass light polarized at 0, 45, and 90 degrees. What is the intensity of the light exiting the last polarizer?

A : 0

B : I0

C : I0 / 2

D : I0 / 4

E : I0 / 8


Matthew 20 30 34
MATTHEW 20:30-34

30. ¶ And, behold, two blind men sitting by the way side, when they heard that Jesus passed by, cried out, saying, Have mercy on us, O Lord, thou Son of David.

31. And the multitude rebuked them, because they should hold their peace: but they cried the more, saying, Have mercy on us, O Lord, thou Son of David.

32. And Jesus stood still, and called them, and said, What will ye that I shall do unto you?

33. They say unto him, Lord, that our eyes may be opened.

34. So Jesus had compassion on them, and touched their eyes: and immediately their eyes received sight, and they followed him.

Other ways to affect polarization
Other Ways to Affect Polarization

  • Birefringence

  • Scattering

  • Optical Activity


Cat’s eyes have pupils that can be modeled as vertical slits. At night, would cats be more successful in resolving

  • Two headlights on a distant car

  • Vertically separated lights on the mast of a distant boat

  • If the two sets of lights are the same distance away, the ability to resolve them would be the same.
