JEE Main 2026 Physics question
An unpolarized light of intensity I₀ passes through polarizer and then through a certain optically active solution and finally it goes to analyser. If the angle between analyser and polariser is 0° and intensity of light emerged from analyser is (3/8)I₀, the angle of rotation of the light by the solution with respect to analyser is degrees.
Answer: 30
Solution
After the polarizer the intensity is I₀/2. The solution rotates the plane of polarization
