a is the answer @Anmol_Seth
hume bhi nhi pata..
It's given in the answer key
Consider Polarised I1 and unpolarised I2
You will have to find I1/I2
Find max intensity, min intensity. I don't think rotation of polarizer has any effect because 360 na.
Are you getting the answer?? @Shubham_Bhagat
I did something in my mind (Trying to learn to do mental calc) and got something like 2(q-1)/1
Def must have thought something wrong but now I'm too lazy to recalc it
@fog856 zara bata de bhai
Unpolaeized gets converted to half irs intensity
While polarized gets converted by a factor of cos²x
Yegjactly what I meant. Made reciprocal mistake when calc mentally xD It's fun to do though
Thanks a lot
