A convex lens of focal length 10 cm is palced at a distance of 12 cm from a wall. Calculate the distance from the lens where an object can be placed so as to form its distinct real image on the wall.

Text Solution

Verified by Experts

`v=+12cm, f=+10cm`
`1/v-1/u=1/fimplies1/12-1/u=1/10`
`u=-60cm`
