Which colour among the seven colours of the white light gets most deviated after dispersion of light through a glass prism?

Correct option is B

The correct answer is (b) Violet.
· When white light passes through a glass prism, it undergoes dispersion, splitting into its seven constituent colors.
· Violet light gets the most deviated because it has the shortest wavelength, and shorter wavelengths refract more in a prism.
Other Options:
· Red: Red light has the longest wavelength and gets deviated the least.
· Indigo: Indigo also deviates more than red but less than violet.
· Orange: Orange deviates less than violet and indigo but more than red.
