The angle of refraction changes based on the medium through which light is passing. When light moves from a less dense medium (like air) to a denser medium (like glass or water), it bends or refracts towards the normal line.

The amount of bending depends on the refractive index of the medium. The refractive index of glass is higher than that of water, meaning glass is optically denser than water.

So, when light moves from air to glass, it bends more compared to when it moves from air to water. This means the angle of refraction is less when light enters glass from air compared to when it enters water from air.

Therefore, the angle of refraction decreases when light moves from air to glass compared to when it moves from air to water. So, the correct answer is B) It decreases.
