(a) State what is meant by plane polarized light
(b) Reflected light from the surface of the water is partially plane polarized. Describe briefly how you could demonstrate this.
(c) Vertically plane polarised light is incident on three polarising filters. The transmission axis of the first polaroid is vertical. The transmission axis of the second polaroid is 45 to the vertical and the transmission axis of the last filter is horizontal. Show that the intensity of the light emerging form the final filter is not zero.
