A convex lens of focal length `5 cm` is used as a simple microscope. What will be the magnifying power when the image is formed at the least distance of distinct vision ?

Text Solution

Verified by Experts

The correct Answer is:

`6`

Here, `f = 5 cm, d = 25 cm, m = ?`
`m = (1 + d//f) = (1 + 25//5) = 6`
