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.
The phenomenon of the formation of the Newton's rings can be explained on the basis of wave theory of light. When a light ray iP1 from an extended monochromatic light source S is a
