Draw a neat labelled diagram showing the plane of vibration and plane of polarisation for polarised light.
Three identical polaroid sheets P1, P2 and P3 are oriented so that the pass axis of P2 and P3 are inclined at angles of 60° and 90° respectively with the pass axis of P1. A monochromatic source S of unpolarised light of intensity I0 is kept in front of the polaroid sheet P1 as shown in the figure. Determine the intensities of light as observed by the observer at O, when polaroid P3 is rotated with respect to P2 at angles θ = 30° and 60°.
How does one demonstrate, using a suitable diagram, that unpolarised light when passed through a Polaroid gets polarised?
Show, with the help of a diagram, how unpolarised sunlight gets polarised due to scattering.
