Different wavelength (colour) of Light when passed through prism refract (bend) by diferent angles...
When red light is passed .. as it is composed by only on single wavelength, it, as a whole, bends by the same angle..
So, there will be a deviation, but no spliiting....
White light has many colours super imposed ( made of many wavelength) and hence each component bends by diferent angles ... causing
what is called, Dispersion.of white light

1) when red light passes through a prism, there is no dispersion (i.e. splitting into colours) as red light is light of one colour. So you only observe refraction where the red light will bends when entering the prism.
2) for white light, both dispersion and refraction take place, so you observe a band of colours when white light passes into the prism.
