B)violet
C)red
D)green

Question

Quizplus · Accepted Answer

The angle of deviation depends on the refractive index of the prism and the wavelength of light. Violet light has the shortest wavelength, and therefore, it experiences the maximum deviation from its original path. On the other hand, red light has the longest wavelength and experiences the minimum deviation. Hence, option B, violet, experiences the greatest angle of deviation.
