i) convex
50=1/f
f=1/50.
ii) .for cancave
30=1/f
f=-30 {for cancave the power is always negative)
(15.) for this we will use the mirror formula in which the relationship b/w image distance(v) ,object distance(u) ,and focal length(f) of a spherical mirror is given.
1/v+1/u =1/f
where v=distance of image from mirror
u=distance of objctfrm mirror
f=focal length of the mirrror
50=1/f
f=1/50.
