Students have asked these similar questions
A clear sheet of polarizing material is placed on top of a second, similar sheet so that
their polarizing axes make an angle o = (5.45x10^1)° with each other. What is the
ratio of the intensity of emerging light to incident unpolarized light? Express your
answer with three significant figures.
When unpolarised light is passed through a polariser, and then through an analyser with its polarising axis at a right angle to the axis of the polariser, the intensity of the remaining light is approximately zero. When a second polarising sheet is placed between the polariser and the analyser, the final intensity is much brighter and clearly non-zero. Explain how this can happen.
Unpolarized light is sent into a system of three polarizing sheets. The angles θ1, θ2, and θ3 of the polarizing directions is measured counterclockwise from the positive direction of the y axis. Angles θ1 and θ3 are fixed, but angle θ2 can be varied. The figure gives the intensity of the light emerging from sheet 3 as a function of θ2. (a) From the intensity plot, what are the possible orientations of the first and third polarizers? Draw a sketch of the situation. (b) What percentage of the light’s initial intensity is transmitted by the three-sheet system when θ2 = 90°? Answer: 7.3%
