A) 1.80, 0.625
B) 0.554, 0.625
C) 1.80, 1.6
D) 0.554, 1.6
Correct Answer: C
Solution :
The refractive index of glass with respect to water is \[_{w}{{\mu }_{g}}=\frac{_{a}{{\mu }_{g}}}{_{a}{{\mu }_{w}}}\] Given,\[_{a}{{\mu }_{g}}=1.5,\] \[_{a}{{\mu }_{w}}=1.33\] \[_{w}{{\mu }_{g}}=\frac{1.5}{1.33}=1.80\] Also, \[_{w}{{\mu }_{d}}=\frac{_{a}{{\mu }_{d}}}{_{a}{{\mu }_{w}}}\] Given, \[_{a}{{\mu }_{d}}=2.4,\] \[_{a}{{\mu }_{w}}=1.33\] \[\therefore \] \[_{w}{{\mu }_{d}}=\frac{2.4}{1.33}=1.6\]
