The color red deviates the least and color violet deviates the most.
When light passes through a prism, it bends (refracts) due to its interaction with the material of the prism. Different colours of light have different wavelengths, and shorter wavelengths refract more than longer wavelengths.
Violet, having the shortest wavelength,bends the most, followed by indigo, blue, green, yellow, orange, and finally red, having the longest wavelength, bends the least
