1)how is the polarization of an electromagnetic wave defined?
a.none of these choices.
b. the polarization is defined by the plane in which the magnetic field is oscillating.
c. the polarization is defined by the direction the wave is traveling.
d. the polarization is defined by the plane in which the electric field is oscillating.
2)In this lab you will be given two polaroid sheets with unlabeled transmission axes. How can you tell, when looking through both polaroid sheets at the same time, if the transmission axes are crossed?
a.If the transmission axes are crossed, you will see one bright line when you look through the polaroid sheets.
b.If the transmission axes are crossed, it will be bright when you look through the polaroid sheets.
c.If the transmission axes are crossed, you will see a bright "+" shape when you look through the polaroid sheets.
d.If the transmission axes are crossed, it will be very dark when you look through the polaroid sheets.
3)In the polarizer + analyzer experiment you will want to start with the transmission axes of the polarizer and the analyzer aligned. How will you know when the transmission axes are aligned?
a.The reading on the detector will be a maximum.
b.The reading on the detector will be a minimum.
c.The 0 degrees reading on the analyzer will be pointing up.
4)Suppose you are wearing polarized sunglasses and looking at a lake on a bright, sunny day. What will happen if you rotate your polarized sunglasses by 90 degrees?
a.The lake will appear equally bright as before you rotated your sunglasses.
b.The lake will appear significantly brighter.
c.The lake will appear significantly darker.
5)Suppose you are looking at unpolarized light coming from an incandescent light bulb. How much will the light intensity you observe be reduced if you look through a single polarizer?
a.50%
b.75%
c.100%
d.25%
