When a object is placed at 25 cm from a concave lens, a virtual image is produced at a distance 10 cm. Calculate the magnification produced by the lens.
Given `u=-25cm`
`v=-10cm`
`m=?`

Text Solution

Verified by Experts

`m=("Height of the image")/("Height of the object")=(v)/(u)`
`=(-10)/(-25)=0.4`
Magnification `m=0.4`
