how will the rainbow look like if viewed from above???And why??

Try it and see. A hose with a spray nozzle that makes fairly uniform-
in-size
drops will do, on a sunny day. Note the relationship between the
position of the sun,
the position of your head, and where you see the centre of the rainbow
to be.
Note especially where the shadow of your head is.

As you will see, it basically looks the same, expect that from above,
you
can often see a complete circle, since the ground doesn't get in the
way.
Why? Think about a mirrored ball, like a shiny Christmas tree
decoration.
Look at it outdoors on a sunny day, and you can see the reflection of
the sun.
Does the reflection of the sun look different if you are above the
mirrored ball?

There's a related phenomenon called "glory", which you can see with
fogs
seen from above from mountains, or dewdrops on the ground.

a rainbow only exist because of the angle of the person veiwing it
and looks different relitive to the position of the veiwer- Hide quoted text -

But because of physiology and the existence of only 3 kinds of color-
sensing
photoreceptors in the human eye, we only have 3-bit color vision,
i.e., White,
Black, and 6 other basic colors. The rest of the color spectrum is
just statistical visible by the limitations of the optical
peremitersof the viewer.
