Question

9. A convex lens of focal length 8 cm forms a real image of the same size as th

object. What will the distance between the object and its image be:
1) 32cm
2) 8cm
3)16cm
4)24cm​

Answer 1

Answer: 32cm

Step-by-step explanation:

Since the focal length of the convex lens is 8cm, the distance between the object and its image be 4f which will be:

= 4 × f

= 4 × focal length

= 4 × 8

= 32cm

The distance between the object and its image is 32cm.
