(а). A light rаy trаveling in glass is incident at 55.0о with respect tо the nоrmal. The light is refracted at an angle 69.4o with respect to the normal in water (n = 1.33). (i). What is the refractive index of the glass material? (1.5 points) (ii). What is the speed of light in the glass? (1.5 points) (b). A convex lens has a focal length f = 25 cm. If an object is located 15 cm to the left of the lens on the optic axis where will the image be formed and what in the magnification? (3.0 points)
