Light incident at Brewster’s angle is reflected and fully
polarized. What are some ways this can be used to generate linear
polarized light? Compare this method to polarizers.
(a) Light reflected at 62.5° from a gemstone in a ring is
completely polarized. Can the gem be a diamond? (b) At what angle
would the light be completely polarized if the gem was in
water?
4) A ray of white light is incident on a prism surface
at some angle, so that you see a rainbow coming out from the other
side. Order the colors with respect to their individual degrees of
refraction, that is, by their refraction angles. (order them from 1
to 4)

Light reflected off a horizontal surface will be
a) partially polarized with the plane of polarization
vertical
b) partially polarized with the plane of polarization
horizontal
c) completely polarized
d) completely unpolarized
At what angle above the horizontal is the sun if sunlight reflected from the surface of a calm lake is completely polarized? What is the plane of the electric-field vector in the reflected light? The plane of the electric-field vector in the reflected light is vertical and perpendicular to the plane of the page. The plane of the electric-field vector in the reflected light is horizontal.
Light of intensity I0 and polarized parallel
to the transmission axis of a polarizer is incident on an
analyzer.
(a) If the transmission axis of the analyzer makes an angle of
46° with the axis of the polarizer, what is the intensity of the
transmitted light?
I0
(b) What should the angle between the transmission axes be to make
I/I0 = 5/8?
°
Light that is polarized along the vertical direction is incident
on a sheet of polarizing material. Only 76% of the intensity of the
light passes through the sheet and strikes a second sheet of
polarizing material. No light passes through the second sheet. What
angle does the transmission axis of the second sheet make with the
vertical? (Let the +y-axis represent the upward vertical direction.
Express your answer as a value between 0° and 180°.) It wants the

Light that is polarized along the vertical direction is incident
on a sheet of polarizing material. Only 77% of the intensity of the
light passes through the sheet and strikes a second sheet of
polarizing material. No light passes through the second sheet. What
angle does the transmission axis of the second sheet make with the
vertical? (Let the +y-axis represent the upward vertical
direction. Express your answer as a value between 0° and 180°.)
Light that is polarized along the vertical direction is incident
on a sheet of polarizing material. Only 93% of the intensity of the
light passes through the sheet and strikes a second sheet of
polarizing material. No light passes through the second sheet. What
angle does the transmission axis of the second sheet make with the
vertical?
A beam of white light is incident
on the surface of a diamond at an angle ?a.(Figure
1) Since the index of refraction depends on the light's wavelength,
the different colors that comprise white light will spread out as
they pass through the diamond. The indices of refraction in diamond
are nred=2.410 for red light and nblue=2.450
for blue light. The surrounding air has nair=1.000.
Note that the angles in the figure are not to scale.
