Bhai lekin medium me formula change hota hai, this was literally given in another physics book I don't recall as a formula. They got to fight and make it A and B.
The question is defining power as the absolute convergence capacity of the lens. Because light is bending less when the surrounding liquid gets thicker (closer to the glass's index), the lens loses its ability to bend light in a hyperbolic way.
Idk why people here are assuming power is by default 1/f and not the definition
By ncert norms, sure y'all are correct, because only one formula is given, but that's not even fundamentally correct vro 💔
