A thin convex lens of focal length 5 cm ...

A thin convex lens of focal length 5 cm is used as a simple microscope by a person with normal near point (25 cm). What is the magnifying power of the microscope ?

Text Solution

Verified by Experts

Here `f=5 cm D = 25 cm M= ?`
`MP =1 + (D )/(F ) = 1+ (25 )/(5 )=6`
