If the angle of incidence is increased for a pair of air – glass...
If the angle of incidence is increased for a pair of air, the angle of refraction will also increase according to Snell's law. Snell's law states that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the refractive indices of the two mediums.

So, as the angle of incidence increases, the angle of refraction will also increase, which means that the light will be bent more as it passes through the air. This can result in a change in the direction of the light ray.
