Polarization of light:a) Polarizers are sometimes referred to as filters. Explain why this is an appropriate name for polarizing materials.b) If you had a single polarizer, how could you determine whether or not light from a room light was polarized when emitted from the bulb?c)Suppose that you have one polarizer with its polarization direction marked. If you were given a second unmarked polarizer, explain how you could determine the polarization direction of the unmarked polarizer. Explain.-(I think I, more or less, understand this, but could use some help on wording it all out. Thanks!)
