Are constellations bound together by gravity?

No. There's no relationship among the stars in a constellation, and they're not bound together by anything. They may be many light years apart, and just happen to lie in roughly the same direction from the Earth so they appear close together as seen by US.

A constellation could be formed from the tree right in front of you, the cat in the grass next to the tree, and the house and two cars five miles away in the same direction as the tree.

They appear to form a pattern or a picture only because the human brain is hard-wired to look for familiar patterns in random stuff. The constellations exist only in our minds.

Refraction occurs through a glass slab why

masha68 [24]

Answer:

One when it enters the glass slab from air and second time when it enters the air through glass slab. When light rays travelling through air enters glass slab, they get refracted and bend towards the normal. Now the direction of refracted ray changes again when it comes out of the glass slab into air.
