A mixture of plane polarised and unpolarised light falls normally on a polarising sheet. On rotating the polarizing sheet about the direction of the incident beam, the transmitted intensity varies by a factor of 4. Find the ratio of the intensities \[{{I}_{p}}\]and\[{{I}_{0}}\], respectively, of the polarised and unpolarised components in the incident beam.
