Solution

The angle of deviation of a light ray depends on the angle of incidence and the wavelength of the light. Since the angle of incidence is said to be same for the light rays of given colors, the angle of deviation will only depend upon the wavelength of the light ray.
The angle of deviation increases with a decrease in wavelength of the light. So, the correct order will be:
Red < Orange < Green < Blue < Violet
