A plane polarised light wave with electric field expressed as (z,t)= Ej cos (kz - cot) is incident from the left on the apparatus as sketched below. Left Y /4 X Fast axis YI /3 P Z Right I w.r.t. the y-axis, The apparatus consists of (from left to right) a polariser with transmission axis at followed by a quarter-wave plate with fast axis along the y-axis, and finally, a polariser with transmission axis, and finally, a polariser with transmission axis at about the x-axis. 1 The intensity of the light emerging out from apparatus on the right is 32 ECE The intensity of the light emerging out from apparatus on the right is CE The state of polarization of light after passing through the quarter wave plate is circular The state of polarization of light after passing through the quarter wave plate is elliptical.
