it deviates its path and meet where water and air surfaces meet.
Without getting too complicated, the "more dense medium"'s gravitational pull alters the path of the light. The ray of light will bend away from the normal.
When light passes into the slab it is changing medium from less to more dense. When that happens the light slows down and bends towards from the normal

A medium with a higher index of refraction, like diamond, is more dense than the medium with a lower index of refraction, like air. If the ray of light is moving from the less dense medium (lower index of refraction), to a more dense (higher index of refraction) the ray of light bends TOWARDS the normal.

If one considers reflective indicies, if the reflective index of the second medium (n2) is larger than the first (n1), the ray bends towards the normal. This means that n2 > n1Since n is defined as c/v, we know that the speed of light is greater in the first medium. Thus, when light changes speed from fast to slow, it bends towards the normal.
