Question 183 of 191

A plane polarized light is incident on a polariser with its pass axis making angle θ\theta with x\mathrm{x}-axis, as shown in the figure. At four different values of θ,θ=8∘,38∘,188∘\theta, \theta=8^{\circ}, 38^{\circ}, 188^{\circ} and 218∘218^{\circ}, the observed intensities are same. What is the angle between the direction of polarization and x\mathrm{x}-axis

Show answer and solution

Answer: (A) 203∘203^{\circ}
