The angle of refraction depends on the wavelength of the light, with shorter wavelengths (blue light) being refracted more than longer wavelengths (red light). This is why the rainbow appears as a spectrum of colors, with red on the outside and violet on the inside.<\/p>\n<p>Diffusion is the scattering of light by particles in a medium. It is not responsible for the formation of rainbows.<\/p>\n<p>Internal reflection is the reflection of light within a medium when the angle of incidence is greater than the critical angle.
