An object is placed at a distance f in front of a concave lens of focal length f. Locate its image.

Text Solution

Verified by Experts

u = -f
Focal length = -f
By lens formula
`(1)/(v) - (1)/(u) = (1)/(f)`
`rArr (1)/(v) + (1)/(f) = (-1)/(f) rArr v = (-f)/(2)`
(i) Image is virtual and (ii)
`m = (-v)/(u) = +(1)/(2)`
