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
Answers
Answer 1
Answer: 32cm
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.
