Does the value of polarising angle depend on the wavelength of light?

Does the critical angle depend on the wavelength of light?

Does the value of polarizing angle depend on colour of light?

A parallel beam of monochromatic light falls normally on a single narrow slit. How does the angular width of the central maximum in the resulting diffraction pattern depend on the wavelength of the incident light?

The critical angle between a given trasparent medium and air is denoted by C.A ray of light in air medium enters this transprent meidum at an angle of incidence equal to polarising angle p.Deduce a relation for the angle of refraction in terms of C.

Show that at polarising angle, the reflected and refracted beams of light are at 90^@ to each other.

How polarising angle is related to critical angle.?

Define the term resolving power of an astronomical telescope.How does it get affeted on increasing the wavelength of light used?
