An unpolarized light of intensity `I_(0)` passes perpendicular through two polaroids, the axis of one is vertical and that of the other is at 30° to the vertical. The intensity of the transmitted light is `(nI_(0))/(2^(n))`. Find the value of n.

A

Plane polarized at `60^@` to the vertical and having intensity of `I_0/4`

B

Plane polarized at `30^@` to the vertical and having intensity of `(3I_0)/8`

C

Plane polarized at `60^@` to the vertical and having intensity of `I_0/2`
