Polarisation

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

The diagonal similarities are due to similar polarising powers for the elements The polarising power is defined as

What is the speed of light in a denser medium of polarising of polarising angle 30^(@) ?

A polariser in used to

The axes of the polariser and analyser are inclined to each other at 60^(@) . If the amplitude of polarised light emergent through analyser is A. The amplitude of unplorised light incident polariser is

The polarising angle for glass is
