When unpolarized light of intensity Io is
incident on a polarizer what is the intensity of
the light that will be transmitted?
A.
B.
C.
D.
E.
Io /2
Io /4
2I o
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
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.

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.
