Detailed Solution

The above statement is false.
Violet has the shortest wavelength among VIBGYOR. So, Violet colour has the minimum speed in a glass prism. Thus, the refractive index property for violet will be maximum. When white light passes through a prism, violet undergoes the maximum deviation and hence appears at the bottom of the spectrum. On the other hand, red undergoes the least deviation and hence appears at the top of the spectrum.
The correct statement would be that violet light is refracted most by the prism.
