hey..frnd...ur answer is here...if u have any prblm in this ...then ask....
height of object, h = 1.5cm
focal length,f =-12cm
u =-18cm
v =?
height of image , h' =?
using mirror formula...i.e. 1/f = 1/u + 1/v
1/v = 1/f - 1fu
= 1/-12 - 1/-18
= 1/ -12 + 1/18
= -3 + 2 / 36 (by taking lcm)
1/v =-1/36
v = -36
m = -v/ u = h'/h
- (-36) / -18 = h' / 1.5
36 / -18 × 1.5 = h'
so...h' is -3cm

use the mirror formula ie 1/v+1/ u=1/ f
