Question
How much brighter is blue sky at 350 nm than at 800 nm?
Approximately 2x
Approximately 25x
Approximately 0.04x
it's the same brightness!
2. The reason why light reflected off a surface often has significant horizontal polarization is that
The atoms reflecting the light can only oscillate at specific frequencies
The atoms reflecting the light can only wiggle parallel to the direction they're re-emitting the light, so they can't produce light having polarization vertical to the surface
The atoms reflecting the light can only wiggle perpendicular to the direction they're re-emitting the light, so they can't produce light having polarization vertical to the surface
None of the above
A.Approximately 2x
B.Approximately 25x
C.Approximately 0.04x
D.it's the same brightness!
