A beam of vertically polarised light is incident normally on a polarising filter. The filter can be rotated so that it is always in a plane perpendicular to the beam. The transmission axis of the filter is initially vertical. beam of vertically polarised light waves transmission axis of polarising filter polarising filter transmitted light The filter is first rotated clockwise by an angle of 30° so that the transmitted light waves have intensity I30.The filter is then rotated clockwise by a further angle of 30°. What is the new intensity of the transmitted light waves?

A source of plane polarised light is observed through two polarising filters. source of polarised light rotated anticlockwise rotated clockwise polarising filters observer The filters are positioned so that the source appears at its brightest. One of the filters is then rotated clockwise and the other filter is rotated anticlockwise through the same angle. How does the source appear when both filters have been rotated 90 and 180 from their initial positions?
