Plane polarized 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 the light, one of the following is observed [MNR 1993]

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
