different for light of different colours

(A) Brewster's law states that the tangent of the Brewster's angle $(i_B)$ is equal to the refractive index $(\mu)$ of the medium: $\tan(i_B) = \mu$. Since the refractive index $(\mu)$ of a medium depends on the wavelength $(\lambda)$ of light (due to dispersion), and different colours of light have different wavelengths, the refractive index varies for different colours. Consequently, the Brewster's angle $(i_B = \arctan(\mu))$ is different for light of different colours.
