Question

A beam of initially unpolarized light passes through a sequence of three ideal polarizers. The angle 0 12 between the axes of the first and second polarizers is 19.7°, and the angle $23 between the axes of the second and third polarizers is 53.3º. 1912 1 EEN 12 What is the ratio of the intensity 13 of light emerging from the third polarizer to the intensity Io of light incident on the first polarizer?

Answer 1

When inpolarized light passes through polarizer then it's insity become half of initial intensity B inten I = Io 2 V using Malus low Iz = I, Cas² Io 2 Cos? (19.7") Iz = 0.443 Io Iz = Iz Costo V Iz = 0.443 To x Cos (53.3°) Iz 0.158 Io Iz Io O. 158 0.16 TA HH Iz To
