Question

An optical system consists of a polarizer (polarizing axis at 30^o relative to the vertical) and analyzer (polarizing axis at 75^o relative to vertical).

1) When unpolarized light with intensity 60 W/m² is incident on the polarizer, the transmitted intensity through the whole system is:

15 W/m2

7.5 W/m2

30 W/m2

zero

2) In the above situation, the transmitted light has its polarization axis at an angle relative to the vertical of:

0 degrees

30 degrees

90 degrees

75 degrees

3)If instead vertically polarized light with intensity 60 W/m² is incident on the polarizer, the transmitted intensity through the whole system will be:

7.5 W/m2

15 W/m2

3.0 W/m2

22.5 W/m2
