When an unpolarized light of intensity $I_0$ is incident on a polarizing sheet,the intensity of light which does not get transmitted is

Choose the $CORRECT$ option for electric field components of unpolarized light passing through a polarizing sheet.

Explain Malus's law and state its mathematical expression.

Polarised glass is used in sunglasses because

Unpolarized light falls on two polarizing sheets placed one on top of the other. What must be the angle between the characteristic directions of the sheets if the intensity of the final transmitted light is one-third the maximum intensity of the first transmitted beam.......$^o$

An unpolarized light of intensity $I_0$ passes through a polarizer,then through a certain optically active solution,and finally through an analyzer. If the angle between the analyzer and the polarizer is $0^{\circ}$ and the intensity of light emerging from the analyzer is $\frac{3}{8} I_0$,the angle of rotation of the light by the solution with respect to the analyzer is . . . . . . degrees.
