2. The prism in the following figure is made out of glass with an index of refraction of n = 1.50. 30 (a) What is the smallest angle 6, for which a laser beam will undergo total internal reflection on the hypothenuse of this glass prism? (b) After reflecting from the hypothenuse, the laser beam exits the prism through the bottom face. Does it exit to the right or the left of the normal? At what angle?(c) If the prism is immersed in water (n = 1.33), what is the smallest angle 6 for which a laser beam will undergo total internal reflection on the hypothenuse of this glass prism? Solution: a) 01 = 17.880 b) 0 = 27.90 left of the normal c) 01 = 37.25
