Question
Does the polarising angle for any transparent medium depend on the wavelength of light?

Answer

Yes, Reason: Angle of polarisation $\text{i}_\text{B}=\tan^{-1}(\text{n})$ and since refractive index varies as inverse of square of wavelength so angle of polarisation decreases with increase of wavelength.
