Which mechanism causes dimming when crossed polarizers rotate?

💡 Explanation

Light extinction occurs because Malus's Law dictates the intensity of light transmitted through a polarizer is proportional to cos²θ; therefore, intensity dims, rather than increases due to reflection because surface effects are minimal.
