Answer 2

1. Magnification :- b) h2/h1

2. Power of a lens:- a) i/f

• Magnification:- Magnification is the process in which the apparant size of object increases , not the physical or real shape of object.

The Formula for Magnification is

M = height of image / height of object

i. e M = h2/h1

• Power of a lens:- Power of lens is defined as the ability of lenses to bend the light falling on it.

Concave lens diverse the ray

Convex lens Converses the ray

Power of lens = 1 / Focal length

So, The correct answer is

Magnification :- b) h2/h1

Power of a lens:- a) i/f
