The different reflections of light through two separate mediums causes the bending of wave fronts associated with light rays. The reflection and refraction is caused by the medium associated with its light rays. Comments.
Light travels in straight lines if the medium it travels through does not change. If light enters a new medium, it might slow down or speed up, because the speed of light is different for different mediums. If light enters the new medium perpendicular to the boundary, it will keep moving in the same direction. But if it hits the boundary at an angle, it will also bend. This bending of light waves due to a change in speed is known as refraction.
