The colour of white light which is deviated the maximum on passing through the glass prism is:(a) blue (b) indigo (c) red (d) orange

(b) indigo

Explanation

In the spectrum of white light, Red light has the longest wavelength and the least frequency (least deviation), whereas, violet light has the shortest wavelength and the highest frequency (maximum deviation), 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 light, indigo will have deviated maximum on passing through the glass prism.
