Horizontally Polarized Light

Vertically Polarized Light

Diagonally Polarized Light

Circularly Polarized Light

Elliptically Polarized Light

Unpolarized Light

Polaroid

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

transmitted?A. Io /2B. Io /4C. 2IoD. zeroE. 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 : 0B : I0

C : I0 / 2D : I0 / 4E : I0 / 8

MATTHEW 20:30-3430. ¶ 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.

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

resolving A. Two headlights on a distant carB. Vertically separated lights on the

mast of a distant boatC. If the two sets of lights are the same

distance away, the ability to resolve them would be the same.
