The refractive index of violet light is most in a glass prism and is the least for the red light. So violet light is most refracted in the glass prism.

When light passes through a prism, the angle of deviation of any light beam is inversely proportional to its wavelengh. Since, violet color has least wave length, it bends the most and the red bends the least.Dhirender Sharma
If these colors most likley as the color spectrum all added on a prism it may reflect on other objects and make a white light.

Red is refracted most and violet is refracted the least when white light passes through a prism.

One device that splits white light into the colors of the visible spectrum is called a prism. It is a triangular piece of glass through which a narrow band of white light can pass. The blue color light is bent most, and the red color light bent the least. So the colors in-between red and blue are seen on a screen as a spectrum. A rainbow is produced when drops of water in the sky have light passing into them, and the light is bent in a similar way, producing the spectrum. So there are many devices that can produce a spectrum of the colors.
