The colour of white light which suffers the maximum bending (or maximum refraction) on passing through a glass prism is:(a) yellow (b) orange (c) red (d) violet

In the spectrum of white light, Red light has the longest wavelength and the least frequency (least deviation, or bending), whereas, violet light has the shortest or least wavelength and the highest frequency (maximum deviation or bending), among all the colours in the visible spectrum.

As we go from red to violet (top to bottom) the wavelength keep on decreasing while the frequency keeps increasing. Thus, among the given colour of white light, violet would suffer the maximum bending (or maximum refraction) on passing through a glass prism.
