HEY LOOK.......USE LENS MAKER FORMULA............

1) 1/F = ( u_l - 1) ( 1/ R₁- 1/R₂₎ ( F=20 , u_{l =}1.5)

NOW WHEN PLACED IN LIQUID..................WE GET............

2)1/f = (u_{l^{/ u}w ^{- 1) (} ^{1 / R}1 ^{- 1/R}2)}

_{DIVIDE 1 BY 2..................}WE GET

F= 80 CM...................

I THINK SO.....IT IS RIGHT.............

THANKU
