WebbWhen a light is incident at polarising angle, the reflected and refracted rays are perpendicular to each other as shown in the figure, where i p is the angle of incidence and r is the angle of reflection, r ′ is the angle of refraction. Given, i p = 57. 5 ∘ Let θ be the angle between the incident ray and the refracted ray. From figure, WebbFigure represents a glass plate placed vertically on a horizontal table with a beam of unpolarised light falling on its surface at the polarising angle of 57o with the normal. The electric vector in the reflected light on screen S will vibrate with respect to the plane of incidence in a [CPMT 1988]
