If you look at a dot on a piece of paper through a calcite crystal lying on the paper, you will see two images of the dot, one of which appears to be nearer to you than the other. From this evidence you can conclude that

Two polarizing films are crossed with their transmission axes making an angle of $\theta$ = 20° with each other. The vectors that represent the plane-polarized wave train passed by the second polarizing film are

When taking a picture of a highly reflecting surface, it is desirable to use a polarizer in front of the camera to cut down on the "glare". Suppose you are taking a picture of a lake where the water is very still. The polarizing axis of the polarizer should ideally be oriented

The dependence of the index of refraction on wavelength is called dispersion. A beam of light (in air) containing red and blue light is incident at an angle of 35 $\degree$ 0 on a glass plate that has an index of refraction of 1.64 for blue light and 1.61 for red light.
