​

Answer 1

The phenomenon of light splitting up into its seven constituent colours is called dispersion. This phenomenon can be observed when white light is passed through a prism.

Answer 2

$\large \mathfrak \red{☆Dispersion \: of \: light:}$

• Dispersion of light is the phenomenon of splitting a beam of white light into its constituent colours on passing through a prism.
• The band of seven colours so obtained is called the (visible) spectrum.
• The dispersion of white light occurs because the colours of white light travel at different speeds through the glass prism.

$\large \mathfrak \red{☆EXPLANATION:}$

• From the above, it is clear that the phenomenon of splitting of white light into seven colours is known as Dispersion of light.
