Plane polarised light is passed through an analyser and the intensity of emerging light is reduced by 75%. Optical vibrations make an angle theta with the axis of analyser. Then theta is

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
