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

• A

  ${90}^{\circ }+\varphi$

• B

  ${\sin }^{-1}\left(\mu \cos \varphi \right)$

• C

  ${90}^{\circ }$

• D

  ${90}^{\circ }-{\sin }^{-1}(\mathrm{sin\varphi }/\mathrm{\mu })$
