Polarized light passes through a polarizer. If the electric vector of the polarized light is horizontal what, in terms of the initial intensity I₀, is the intensity of the light that passes through a polarizer if the polarizer is tilted 22.5° from the horizontal? A) 0.854I₀ B) 0.147I₀ C) 0.191I₀ D) 0.011I₀

Quizplus · Accepted Answer

The intensity of light passing through a polarizer is given by Malus's Law: I = I₀cos²θ. For θ = 22.5°, cos²(22.5°) ≈ 0.854. Thus, the intensity is approximately 0.854I₀.
