Choose the $CORRECT$ option for electric field components of unpolarized light passing through a polarizing sheet.
- AAn electric field component parallel to the polarizing direction is absorbed, and the component perpendicular to the polarizing direction is transmitted.
- BAn electric field component parallel to the polarizing direction is transmitted, and the component perpendicular to the polarizing direction is absorbed.
- CAn electric field component parallel to the polarizing direction is rotated through some angle, and the perpendicular component is transmitted.
- DAn electric field component parallel to the polarizing direction is transmitted, and the perpendicular component is rotated through some angle.

Four polaroids are placed such that the optic axis of each is inclined at an angle of $30^{\circ}$ with the optic axis of the preceding one. If unpolarised light of intensity $I_0$ falls on the first polaroid,the intensity of light transmitted from the fourth polaroid is $[\cos 30^{\circ} = \sqrt{3} / 2]$.

View SolutionStatement-$I$: On viewing the clear blue portion of the sky through a calcite crystal,the intensity of transmitted light varies as the crystal is rotated.
Statement-$II$: The light coming from the sky is polarized due to the scattering of sunlight by particles in the atmosphere. The scattering is largest for blue light.
