Question

In which of the following, scattering of light does not takes place?

• A. Blue colour of the sky
• B. Colour of deep sea
• C. Reddening of the sun
• D. Rainbow

Answer 1

The correct option is D

Rainbow

Scattering is the irregular and partial reflection of light. In this phenomenon, when light falls on a rough surface or on tiny particles, it reflects in all direction whereas dispersion is the phenomenon of splitting up of composite light into its constituent colours. The blue colour of the sky, the colour of the deep sea and the reddening of the sun are all examples of the scattering of the light whereas in the rainbow, the white light splits into its constituent colours, which is the phenomenon of dispersion.
