An object is seen thorugh a simple microscope of focal length 12 c. Find the angular mgnification produced if the image is formed at the near pointofhe eye which is 25 cm away from it.

Verified by Experts

The angual rmagnification produced by a simple microscope when the image is formed at the near point of the eye is given by
`m1+D/f`
Here f=12 cm, D=25cm. Hence
`m=1+25/12=2.08`
