An unpolarised light beam of intensity I₀ is incident on a fixed polariser P₁ . The transmitted light then passes through an analyser P₂ which can be rotated. Consider the following statements: (A) The intensity of light transmitted through P₁ is I₀ 2 and is independent of the orientation of P₁ . (B) The final intensity of light transmitted through P₂ is maximum when the angle between the transmission axes of P₁ and

Step-by-step solution

Statement (A) is correct: When unpolarised light passes through a polariser, the transmitted intensity is exactly half of the incident intensity, regardless of the polariser's orientation. Statement (B) is incorrect: According to Malus's law, I = I_ max ^2 . When the angle = 90^ , 90^ = 0 , so the intensity is minimum (zero), not maximum. Statement (C) is correct: The intensity follows I = I_ max ^2 , which is a cosine-squared curve. Statement (D) is correct: The intensity after P₁ is I₁ = I₀ 2 . After P₂ , the int
