Question

why are we not able to see complete rainbow in all the places?

Answer 1

After rain,some water particles remain suspended in air and act as prism to the light falling on them.White light after falling on these particles,break into its constituent colours.The colours are arranged according to wavelength.Red has maximum wavelength and violet minimum.Now the intensity of light varies from place to place.The colours often tend to merge with one another as rainbow is a continuous spectrum.Hence a complete rainbow is not seen at all places.

Explanation:

Theoretically rainbows are always created in complete circle, but how you see rainbow depends on where you are standing.

“White light” consist of several colors. And under normal conditions we cannot differentiate between those. When Rainbow is formed, this white light gets split into different colors & thus we see individual colors separately.

For rainbow to form we need sunlight, water droplets in air & human eye. Rainbows “happen” when sun hits a raindrop. The light bends when it hits the drop, reflects off the back of the drop, and then bends again as it leaves the drop.

Different colors bends at different angles, thus if this reflected ray hits human eye we do see only one color from that drop (direction/angle), and not all colors forming white light.

But we see all color coming from different direction (which makes a pattern we call Rainbow). Like in image below from one top we are getting Red, and from another drop at different angle we get Violet.
