Solution
The correct option is D Violet
'Dispersion of Light' can be defined as the splitting of white light when it passes through a glass prism into its constituent spectrum of colors (i.e.violet, indigo, blue, green, yellow, orange and red).
The light waves are refracted as they enter and leave the prism. The shorter the wavelength of the light, the more it is refracted. As a result, the red light is refracted the least and violet light is refracted the most, causing the coloured light to spread out to form a spectrum.
From the figure, it is clear that violet refracts the most due to its low wavelength.
