← ScienceWhich mechanism causes dimming when crossed polarizers rotate?
A)Malus's Law reduces light transmission✓
B)Fresnel reflection increases surface losses
C)Brewster's angle eliminates reflections
D)Snell's law refracts exit angles
💡 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.
