The shape of the rainbow is like a bow. Why it does not appear as full circle or some other geometric form ?
Inside of rainbow appears brighter than outside ? Why it is so ?

Rainbows are an arc which is part of a full circle because of the way they are formed. You see a rainbow on an arc about 42 degrees around the anti solar point (the shadow of your head).
It is bright inside the primary rainbow because of scattered light. See a more detailed explanation of how a rainbow is formed.

It also brighter outside the secondary rainbow, and the dark band between the 2 is sometimes called "Alexander's Band"

a rainbow i actually a full circle.. as you are on part of the earth you are unable to see the full circle... and for the colour... it is the wavelength of different colours..
