violet or the blue side of rays refract more
Refraction is the change in direction of a light beam commonly caused as it passes from one medium to another. Snell's law relates the angle of incidence and angle of refraction by n1 * sin(theta1) = n2 * sin(theta2).
The reason different wavelengths of light refract at different angles in a medium (such as water or glass) is because the index of refraction (n2) varies by wavelength, this variation with wavelength is known as dispersion.
In most materials that you would observe refraction, the index of refraction decreases with wavelength. This is called normal dispersion. (If the index of refraction increases with wavelength, it's called anamolous dispersion.)
Thus, in glass (prisms) or water (rainbows), which exhibit normal dispersion, the index of refraction is greater for shorter wavelengths. Violet light, which is the shortest wavelength of visible light, will refract the most.
by the way- this is not my thought, I got this from yahoo! UK and Ireland' from a guy named askbrian

Which color of light is dispersed most by a prism?
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.
What colour of light is refracted most?
purple
Which light is deviated most and which light deviated least when a ray of white light passes through a prism?
Red is refracted most and violet is refracted the least when white light passes through a prism.
What color is refracted most when passing through a prism?
Violet
What does the perceived color of each water droplet in a rainbow depend on?
The wavelength, or perceived color of each water droplet that makes up a rainbow, is determined by the amount by which light is refracted. Blue light (shorter wavelength) is refracted at a greater angle than red light. ChaCha.
What color is refracted the most?
white light

What colour of light is refracted most?
purple
What makes the color of rainbows?
light refracted by raindrops appear to be different colours
Rainbow like band of color that is seen when white light is refracted?
It is called the spectrum of white light.
Which light is deviated most and which light deviated least when a ray of white light passes through a prism?
Red is refracted most and violet is refracted the least when white light passes through a prism.
Which color is most refracted in a 60 degree prism?
Violet
What color is refracted most when passing through a prism?
Violet
What does the perceived color of each water droplet in a rainbow depend on?
The wavelength, or perceived color of each water droplet that makes up a rainbow, is determined by the amount by which light is refracted. Blue light (shorter wavelength) is refracted at a greater angle than red light. ChaCha.
What color is least bent by a prism?
Red light is refracted the least by a prism as it has the longest wavelength.
When is light refracted?
light is refracted when it travels through air and then through glass
Why the sky appears to change color and what cause this to happen?
change in the composition of the gasses and the angle of refracted light
