A beam of vertically polarised monochromatic light is incident on a polarising filter, as shown in Fig. 5.1.
The transmission axis of the filter is initially vertical and the transmitted light beam has the same intensity as the incident light beam. The filter may be rotated about the direction of the light beam to change the angle of the transmission axis to the vertical.
State one angle of the transmission axis to the vertical that results in no transmitted light beam.
