Humans have little or no sensitivity to polarized light, and no
sensitivity at all to ultraviolet light while many invertebrates
such as insects do. In what way do you think this would be useful
to an organism?
1. In humans, darker skin color is adaptive at latitudes
near the equator (where ultraviolet light is most intense) because
UV light
stimulates synthesis of folic acid
causes breakdown of folic acid
stimulates synthesis of vitamin D
causes breakdown of vitamin D
2. In humans, lighter skin color is adaptive at
latitudes far from the equator because UV light
stimulates synthesis of folic acid
causes breakdown of folic acid
stimulates synthesis of vitamin D ...
As we know, linearly polarized light corresponds to a pure state
and non-polarized light is in a mixed state.
Considering statistical mechanics, please state and show whether
a circularly polarized light is in a pure state or a mixed
state.
Consider a right circularly polarized light and a left
circularly polarized light having common angular frequency and wave
number both propagating in the z - direction. a). Write out the
appropriate expressions representing right circularly polarized
light and a left circularly polarized light respectively. b)
Combine the two waves and state the conditions under which the
combination to yeild a plane wave.

Polarized light is to have its polarization plane rotated by 90
degrees. In which of the following cases does the final beam have
the greatest intensity?
Select one:
a. 1 polarizing filter, rotating the beam by 90 degrees
b. 3 polarizing filters, both rotate the beam by 30 degrees
c. 6 polarizing filters, each rotating the beam by 15
degrees
d. None of the above, polarized light can't be rotated
please explain the answer think it is C.
A laser produces light that is polarized in the vertical direction. The light travels in the positive y-direction and passes through two polarizers, which have polarizing angles of 36.1
