How can white light be dispersed?

By shining the light through a prism

When white light is passed through a glass prism, it gets split into colours which is in the order of violet, indigo, blue, green, yellow, orange and red. Newton explained the dispersion of white light. He made white light fall on a prison. This caused dispersion of white light into seven colours. Newton then placed an inverted prism in the path of colour band of seven colours. Then he saw the white light back again. The process of white light splitting into its constituent colours is termed as dispersion.
