Detailed Solution

When light travels from air to glass, then angle of incidence

>

angle of refraction.
It is known that the ray of light bends towards the normal when it travels from an optically rarer medium to an optically denser medium and moves away from the normal when it travels from an optically denser medium to an optically rarer medium. Also, the air is optically rarer, and the glass is optically denser. Also, the angle of incidence refers to the angle made by the incident ray with the normal, and the angle of refraction refers to the angle made by the refracted ray with the normal. Since glass is denser than air, the incident ray bends towards the normal, and the angle of the refraction decreases. Hence, it can be said that the angle of incidence > angle of refraction.
