Light becomes polarized at the Brewster angle because when light strikes a surface at this specific angle, the reflected light waves vibrate only in one plane, parallel to the surface. This occurs because at the Brewster angle, the reflected and refracted rays are perpendicular to each other, causing the reflected light to be polarized. This phenomenon is a result of the mathematical relationship between the angle of incidence and the refractive indices of the two media involved. **
