A mixture of plane polarised and unpolarised light falls normally on a polarising sheet. On rotating the polarising sheet about ther direction of the incident beam, the transmitted intensity varies by a factor of 3. The ratio of intensities I_p and I_p of the polarised and unpolarised components in the incident beam is

A mixture of plane polarised and unpolarised light falls normally on a polarising sheet. On rotating the polarising sheet about the direction of the incident beam, the transmitted intensity varies by a factor 4. Find the ratio of the intensities I_(P) and I_(0) respectively of the polarized and unpolarised components in the incident beam. Next the axis of polarising sheet is fixed at an angle of 45^(@) with the direction when the transmitted intensity is maximum. Then obtain the total intensity of the transmitted beam in terms of I_(0) . [(3)/(2),(5I_(0))/(4)]

The polariser and analyser are inclined to each other at 60^(@) . The intensity of polarised light emerging from polariser is I. The intensity of the unpolarised light incident on the polariser is
