Question

polarization question ! help me

Answer 1

unpolarized light passes through 2 Polaroid sheets . the axis of the first polarizer is vertical , and that of the second is at tetha degree to the vertical . If only 25% of the initial light is transmitted , compute the axis of the second polarizer .

Answer 2

i know that I need to use Malus Law ; I = Io cos^2 theta

Answer 3

id need to knnow more information as to the properties of a polarized sheet

Answer 4

that's the info were given by the question

Answer 5

i imagine the sheet has slits in it of a certain height and width. but thats just an assumption, im trying to google what this process is like

Answer 6

something like this

Answer 7

i think

Answer 8
