Plane polarised light is passed through ...

Plane polarised light is passed through a polaroid. On viewing through the polaroid we find that when the polaroid is given one complete rotation about the direction of light

The intensity of light gradually decreases to zero and remains at zero

The intensity of light gradually increases to a maximum and remains at maximum

There is no change in intensity

The intensity of light is twice maximum and twice zero
