Question

Which of the following colours CANNOT be found in a rainbow?
1. Pink
2. Orange
3. Green
4. Yellow

Answer 1

Correct Answer - Option 1 : Pink

The correct answer is Pink.

•  Among the given colors Pink colour is not found in a rainbow.
• 7 colours of the rainbow are- red, orange, yellow, green, blue, indigo and violet
• In the process of formation of a rainbow after a rain shower, sun light is dispersed by tiny water droplets.
• A rainbow is formed when it rains and there’s sunshine simultaneously. 
• Each raindrop is made of a different shape and has a different consistency as compared to a glass prism, still, it affects light in a similar fashion. 
• One can see the seven constituent colors -red, orange, yellow, green, blue, indigo and violet when white light (sunlight) hits a collection of raindrops at a fairly low angle.
• When the white sunlight travels from air into the drop of water, the constituent colors of light slow down to varying speed and frequencies.
• When violet light enters the raindrop it bends at a relatively sharp angle. Some of the light then passes back out into the air, and the rest is reflected back. Some of that reflected light passes out of the drop, bending as it moves back into the air again.
• This way, each raindrop disperses the white sunlight into its constituent colors
