Rainbow is formed due to following reasons:
Refraction, Dispersion of white light , total internal reflection.
Essential condition for formation of rainbow:
1. Presence of raindrops
2. To view rainbow, sun should be at your back.
Actually Rainbows form full circles. But it depends on the position and angle of observer and incident angle of sunlight.
The angle between the incoming and the outgoing rays can between 0 degrees to 42 degrees. We observe bright rainbow when the angle between incoming and outgoing rays is near the maximum angle of 42 degrees.
Although, each drop disperses a full spectrum of colours, an observer in a position to see only a single colour from any one drop depending upon its position.
To see red colour, one must look at 42 degrees (angle between incident and reflected )and violet colour at 40 degrees.
So, if we look at an angle between 40 degrees and 42 degrees we can see remaining colours of rainbow
