Solution

The correct option is B
$F_{2}$

The diverging rays will seem to meet at the point $F_{2}$ . The parallel rays coming from infinity gets diverged on passing through a concave lens. These diverged rays, if traced back, seem to originate from the point $F_{2}$ .

Q. Fig 28.86 shows a simple version of zoom lens. The converging lens has focal length

f_{1}

and diverging lens has focal length

f_{2}

| f_{2} |

. The two lenses are separated by a variable distance d that is always less than

f_{1}

. Also, the magnitude of the focal length of the diverging lens satisfies the inequality

| f_{2} | > f_{1} - d_{0}

. To find the focal length of the combination lens consider a bundle of parallel rays of radius

r_{0}

entering the converging lens.
1. Find the radius of the ray bundle
