b. they speed up and turn slightly.
What is the refraction theory?
Whilst a ray passes from a much less dense medium (along with air) to a denser one (consisting of glass), the ray is bent, or refracted, in one of this way that it emerges from the interface in a course that lies closer to the perpendicular, which calls "regular", to that interface.
Light refracts every time it travels at an attitude right into a substance with an exclusive refractive index (optical density). this variation of the path is a result of an alternate in velocity. As instance, whilst light travels from air into water, it slows down, inflicting it to hold to journey at a specific angle or direction.
