Quick oral answer

$The colors 'P' and 'Q' are violet and red, respectively, due to the dispersion of white light by the glass prism.$

The dispersion of white light by a glass prism is a fundamental concept in physics. The diagram shows the separation of white light into its constituent colors, with violet and red being the two extremes. This phenomenon is due to the different refractive indices of the glass prism for different wavelengths of light.

$The dispersion of white light by a glass prism was first observed by Isaac Newton in 1666.$
