Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

1/4 wp: output elliptical or circular polarisation 1/2 wp: relative axis of elliptical polarisation, compared to input, will be rotated around by 180deg. The output will still be elliptically or circularly polarised. Configuration 1: it will be eliptical or circular as effect of half plate will be on rotation only. Configuration 2: it will be again eliptical or circular only because of quarter plate. half plate may be at any angle it's not going to affect the shape of output wave. same is true for Configuration 3..
Sir , a QWP introduces a phase diff of π/2 and HWP introduces a phase diff of π but I am not able to understand what change is there when they are rotated
π/2 phase difference results to conversion of ppl into epl or cpl and vice versa. π phase difference results as change in direction of rotation (clockwise -> anticlockwise and vice versa) . as result, π phase difference DON'T affect ppl light.
ok sir
sir and if the QWP or HWP are inclined at a certain angle then
No change as input is given unpolarized light.
