Question

divergence of convergence is correct or convergence of divergence is correct in power of lens please tell​

Answer 1

Let's say we have a cat standing on one side of a converging lens. ... Practice: Power of lens ... I want to know that a.. . convex lens forms virtual or real image ... 

Answer 2

Answer:

Explanation:

This is defined as inverse of focal length of thelens. For convex lens since f is positive and it converges the rays , it's power is positive. Now, concave lens has negative focal length and it diverges the rays ,so it's power is negative. The diverging power then may be defined as negative of converging power.
