Person A wear glass of optical power `P_(1)` = +2D in air. The glass have refractive index `1.5` .Now he jump into a swimming pool. The refractive index of water in the swimming pool is `(4)/(3)`. What will be the power (in D) of glass in water.

Two persons A and B wear glasses of optical powers (in air) P_1 = + 2 D and P_2 = + 1D respectively. The glasses have refractive index 1.5. Now they jump into a swimming pool and look at each other. B appears to be present at distance 2m (f rom A) to A. A appears to be present at distance 1m (from B) to B. The refractive index of water in the swimming pool, in the form (X)/(10) and find X.
