Water is more dense than air so when light travels from air to water, the light slows down. This causes the light to bend which way relative to the normal?

In the given case, the light travels from the rarer medium to the denser medium.

When the light enters the denser medium, due to the refraction, it bends towards the normal such that the angle of incidence is more than the angle of refraction.

Thus, the light bends towards the normal.
