Correct Answer: C
Solution :
[c] : When light travels from medium of refractive index \[{{\mu }_{2}}\]to medium of refractive index \[{{\mu }_{1}}\]at a single spherical surface, the formula used is \[\frac{{{\mu }_{1}}}{v}-\frac{{{\mu }_{2}}}{u}=\frac{{{\mu }_{1}}-{{\mu }_{2}}}{R}\]You need to login to perform this action.
