Question

TuteeHUB · Accepted Answer

$$\frac{\mu \,\varepsilon }{{{\mu }_{0}}{{\varepsilon }_{0}}}$$

TuteeHUB · Answer

$$\sqrt{\frac{\mu \varepsilon }{{{\mu }_{0}}{{\varepsilon }_{0}}}}$$

TuteeHUB · Answer

$$\sqrt{\frac{{{\mu }_{0}}{{\varepsilon }_{0}}}{\mu \varepsilon }}$$

TuteeHUB · Answer

$$\sqrt{\frac{\mu {{\mu }_{0}}}{\varepsilon \,{{\varepsilon }_{0}}}}$$

1.	If \[{{\varepsilon }_{0}}\] and \[{{\mu }_{0}}\] are respectively, the electric permittivity and the magnetic permeability of free space, \[\varepsilon \] and \[\mu \] the corresponding quantities in a medium, the refractive index of the medium is [IIT-JEE 1982; MP PET 1995; CBSE PMT 1997]
A.	\[\sqrt{\frac{\mu \varepsilon }{{{\mu }_{0}}{{\varepsilon }_{0}}}}\]
B.	\[\frac{\mu \,\varepsilon }{{{\mu }_{0}}{{\varepsilon }_{0}}}\]
C.	\[\sqrt{\frac{{{\mu }_{0}}{{\varepsilon }_{0}}}{\mu \varepsilon }}\]
D.	\[\sqrt{\frac{\mu {{\mu }_{0}}}{\varepsilon \,{{\varepsilon }_{0}}}}\]
Answer» B. \[\frac{\mu \,\varepsilon }{{{\mu }_{0}}{{\varepsilon }_{0}}}\]

If \[{{\varepsilon }_{0}}\] and \[{{\mu }_{0}}\] are respectively, the electric permittivity and the magnetic permeability of free space, \[\varepsilon \] and \[\mu \] the corresponding quantities in a medium, the refractive index of the medium is [IIT-JEE 1982; MP PET 1995; CBSE PMT 1997]
