When an object is placed at 25 cm from a concave lens, a virtual image is produced at a distance of 10 cm. Calculate the magnification produced by the lens.

Text Solution

Verified by Experts

Given
Object distance , u=25 cm
virtual image distance , v=-10 cm
To find : Magnification , m= ?
`m=("Distance of the image")/("Distance of the object")=v/u`
`=(-10)/(25) =-0.4`
Magnification ,
m=-0.4
