A) \[\frac{2.6}{1.5}\]
B) \[\frac{1.5}{2.6}\]
C) \[\frac{1.5}{1.3}\]
D) \[\frac{1.3}{1.5}\]
Correct Answer: C
Solution :
Here: Refractive index of water with respect to air = 1.3 Refractive index of glass w.r.t. air = 1.5 From the formula the refractive index of glass with respect to water is grating \[=\frac{Refractive\text{ }index\text{ }of\text{ }glass\text{ }w.r.t.\text{ }air}{Refractive\text{ }index\text{ }of\text{ }water\text{ }w.r.t.\text{ }air}\] \[=\frac{1.5}{1.3}\]
