32. Electromagnetic Waves

Why does a skier wear polarized glasses instead of glasses that are used for reading?

In three-dimensional projection systems, what is the primary role of polarization filters?

In the context of polarization, which component of the electromagnetic wave is primarily affected by polarization filters?

When two ideal polarizing filters are overlapped so that their transmission axes are at right angles ($90°$) to each other, what happens to the intensity of unpolarized light passing through both filters?

Which of the following is an example of polarization?

Which statement best describes a polarizing filter with vertically aligned chemical molecules?

In each of the following cases, initially vertically polarized light enters the polarizing apparatus with the same initial intensity. Which polarizing apparatuses will cause the light to exit with the largest intensity, 90° from its initial polarization? 

a) A single polarizing filter, oriented 90° from the vertical 

b) Two polarizing filters, the first 45° from the vertical and the second 90° from the vertical 

c) Two polarizing filters, the first 60° from the vertical and the second 90° from the vertical 

d) Two polarizing filters, the first 30° from the vertical and the second 90° from the vertical.
