A beam of light is incident from the air on a transparent substance at an angle of 56 with respect to the normal, part of the beam is reflected and the other is refracted. It is observed that the reflected and refracted beams are mutually perpendicular. What is the refractive incidence of the transparent substance? What can you say about the reflected beam? Since you know both indices of refraction, suppose a light beam is incident from the medium with the higher index of refraction to the medium with the lower index of refraction. What is the critical angle to achieve total internal reflection?
