Open in App
Solution
The correct option is C partially reflected and partially refracted
The ray which travels from a denser medium to a rarer medium at an angle less than critical angle is partially reflected and partially refracted, no matter how smooth the surface. If it is incident at critical angle or higher than that, then the ray does not refract at all.
