Ahorizontal, parallel-sided plate of glass having a refractive index of 1.52 is in contact with the surface of water in a tank. a ray coming from above in air makes an angle of incidence of with the normal to the top surface of the glass. (a) what angle does the ray refracted into the water make with the normal to the surface? (b) what is the dependence of this angle on the refractive index of the glass?
