Answer 2

Answer:

Dispersion of white light is defined as splitting of white light into seven constituent colours when passed through the prism. When white light is passed through a glass prism it splits into its spectrum of colours (in order violet, indigo, blue, green, yellow, orange and red) and this process of white light splitting into its constituent colours is termed as dispersion.
