Explanation:
Detailed explanation-1: -therefore the angle of refraction is 19.2°.
Detailed explanation-2: -In the analysis, when the light rays travel from air to medium of crown glass, such that it strikes the surface of crown glass by making some angle, then the angle by which the light rays being refracted from the surface is called the angle of refraction.
