Explanation:
The mirror formula states that if focal length(f), object distance(u) and image distance(i) then-
1/f = 1/v + 1/u
In a convex mirror,
Object distance is always negative
Image distance is always positive
Focal length is always negative
In a concave mirror,
Object distance is negative
Image distance is negative
