Question

In the order of decreasing frequency. which of the following is correct? Star #1 it approaching the Earth with speed v Star #2 is receding from the Earth with same speed v. Measurements of the same spiral line from each of the stars show Doppler shifts in frequency. The light from which star will have the larger magnitude shift in frequency? Unpolarized light of Intensity Io passes through two sheets of ideal polarizing mateail if the transmitted intensity is 0.375 Io. What is the angle between the polarizers? A young's double slit interference experiment is performed in air and then the apparatus is submerged in water. What happens to the fringe separation and what can be used to explain the change, if any ?

Explanation / Answer

11. According to Malus law, the intensity of transmitted polarised light

          I=I0cos2 (theta)

              0.375 Io = I0 cos2 (theta)

               cos2 (theta)= 0.375      ,    cos(theta)= square root(0.375) =0.61237

                   theta= cos-1 (0.61237)

                          theta= 520 14'
