• Sep 8, 2025 Intensity Of Unpolarized Light Through Polarizer on axis, is blocked. Therefore, the intensity of the light emerging from the first polarizer (I₁) is exactly half the intensity of the incident unpolarized light (I₀): I₁ = I₀/2 Now, if we introduce a second polarizer (analyzer), Malus' Law comes into play.
