Mirror formula for dertermining the focal length of mirror => 1/f =1/v + 1/u
focal length of cancave mirror is negative and focal length of convex mirror is positive.
object distance= u = -25 cm (object distance is always negative for a real object)
focal length of cancave mirror is negative and focal length of convex mirror is positive.
object distance= u = -25 cm (object distance is always negative for a real object)

1\F=1\U+1\V
F=FOCAL LENGTH
U=OBJECT DISTANCE
V=IMAGE DISTANCE
F=FOCAL LENGTH
U=OBJECT DISTANCE
V=IMAGE DISTANCE
