Solution

The correct option is B Velocity of light for violet is less than the velocity of light for red
When white light passes through a dispersive medium it breaks up into various colours because velocity of light for different colours is different as they differ in wavelength. Secondly, velocity of light for violet is less than the velocity of light for red, as it undergoes maximum deviation
