Splitting of a beam of white light into its constituent colours

• GP Light

Which one of the following processes explains the splitting of a beam of white light into its constituent colours?

1. Polarization
2. Dispersion
3. Diffraction
4. Reflection

Answer

Dispersion is the separation of white light into colours. The most common example of dispersion is rainbow, in which dispersion causes the separation of a white light into components of different wavelengths (different colors). 

The correct option is B.
