A biconcave lens of power P vertically splits into two identical plano concave parts. The power of each part will be

Answer»

2P
`(P)/(2)`
P
`(P)/(sqrt(2))`

SOLUTION :For a BICONCAVE lens, power P - `(N-1) [(1)/((-R))-(1)/((+R))]-(2(n-1))/(R)`UL for a verlically splitted lens, power P= (n -1) `[-(1)/(R )]=- ((n-1))/(R ) = (P)/(2)`
