After being dispersed form a prism, a white light splits into seven colours. Which colour will be refracted the most?
Red
Green
Blue
Violet
From the figure, it is clear that violet refracts the most due to its low wavelength.
A prism splits a beam of white light into seven colours because different colours have different
Statement 1: When white light ray passes through a prism it disperses into seven different colours, and this phenomenon is called dispersion.
Statement 2: Refraction depends upon the wavelength of light and since different colours have different wavelengths, they are refracted at different angles and so they are split into the colour spectrum.
