(a) Fig. 1.1 shows two polarising filters P and Q, placed between a lamp and a detector.
Fig. 1.1
lamp detector
P Q
Initially the polarising filters are orientated with their planes of polarisation parallel to each other.
Q is then rotated, as shown, about the beam of light travelling from the lamp to the detector.
(i) Fig. 1.2 is a graph of the light intensity registered by the detector against the angle of rotation of
polaroid Q from its initial position.

angle of rotation / °
Label the horizontal scale, angle of rotation / ° of the graph with the appropriate scale.

(ii) What characteristic of a light wave allows it to be polarised?
