Answer Details
When light passes through a prism, it is refracted at both its entry and exit faces. The amount of refraction depends on the wavelength of the light, with shorter wavelengths (violet and blue) being refracted more than longer wavelengths (red and orange). As a result, white light, which is a mixture of all colors, is separated into its constituent colors, forming a spectrum of colors. The angle of deviation, which is the angle between the incident ray and the emergent ray, decreases in the order of violet, blue, green, yellow, orange, and red. Therefore, the correct option is: blue, red and orange.
