On entering the air, light's velocity decreases as it enters a rarer medium.

speed of light is higher in air than water.
No, it is higher in water as water is denser than air.

Since, water is denser medium than air.
Therefore,when a ray of light passes from water to air,it bends away from it's normal. And also the speed of light increases.
