Answer:glass
Explanation: A ray of light strikes a glass plate at an angle of 60° with the glass surface. If the reflected and refracted rays are at right angles to each other. The angle of refraction = The angle of incidence = The refractive index of the glass will be. Hence, The refractive index of the glass will be 1.732.
