11.5.1
Describe what is meant by polarized light:

• Polarized light is when the light waves are oriented in a particular direction, it only vibrates on a single plane rather than all directions.

11.5.2 & 11.5.3

State and apply Brewster's laws

• Brewster's law states that an angle of incidence at which light with a particular polarization/orientation is perfectly transmitted through a surface, with no reflection. An example would demonstrate this would be a pond and the reflection from the surface of the water. If a fisherman was to wear polarized sunglasses and sit at the angle too the water as stated in Brewster's law, he would see no reflection from the sun at all.

Q28 : Calculate Brewster's angle for water (refractive index 1.5)

(Sorry I don't know why this isn't rotating)

Q29 : Explain why a fishermen in the middle of the day during summer would not find his polaroid glasses very effective

• Since the sun would be directly over him, the angle would be too great and no where near Brewster's ideal angle.
