Malus' law (E.L. Malus):
The light intensity I of a ray along initial intensity I0 travelling by a polarizer at an angle theta among the polarization of the light ray & the polarization axis of the polarizer is specified by I = I0 cos2 theta.
Draw a ray diagram to show the formation of image of an object placed among the optical centre and focus of the convex lens. Write the characteristics of image formed. Using this d
