A ray of light passes from glass to water. The angle of incidence in the glass is 28o , if the refractive indices of glass and water to be 1.52 and 1.33, respectively. (i). What is the angle of refraction in the water? (1.5 points) (ii). At what angle will total internal reflection occur between the glass-water interface? (2.0 points)
