The diagram shows light Io passing through three polarising sheets. The intensity of the light I3 through the final sheet is 80 units. The transmission axis of the first sheet is vertical and the transmission axis of the end analyser is horizontal. The angle between the planes of polarisation of first and second sheets is 30°. Io Transmission axis I1 - 12 Determine the intensity of the light incident on the polariser, Io. I3 = 80 units -
