■ Glass and water are thicker and heavier than air. They are said to be 'denser' than air. What happens is that light slows down when it passes from the less dense air into the denser glass or water.
■ Light passing into an optically densermedium is bent towards the normal; light passing into an optically lessdense medium is bent away from the normal. Materials such as glass, waterand paraffin are said to be optically denser than air.

Why Glass & water Is Optically Denser Than Water?
Glass is the denser than water because speed of light in glass is less than that of water.
If Refractive index is more bending of light is more and speed of light will be less.
