$A$ ray of light is incident on the surface of a glass plate at Brewster's angle $\phi$. If $\mu$ is the refractive index of glass with respect to air,then the angle between the reflected and the refracted ray is:

  • A
    $90^{\circ} + \phi$
  • B
    $\sin^{-1}(\mu \cos \phi)$
  • C
    $90^{\circ}$
  • D
    $90^{\circ} - \sin^{-1}(\sin \phi / \mu)$
