The angle of refraction for a ray of light traveling through an ice cube is 35 degrees, (a) now suppose the ice melts, but the angle of refraction remains the same, is the corresponding angle of incidence greater than, less than, or the same as it was for the ice? Explain. (b) Calculate the angle of incidence for part (a).
