Optics: JEE Main 2026 Physics question

When an unpolarized light falls at a particular angle on a glass plate (placed in air), it is observed that the reflected beam is linearly polarized. The angle of refracted beam with respect to the normal is_______. ($\tan^{-1}(1.52)=57.7^\circ$, refractive indices of air and glass are 1.00 and 1.52, respectively.)
