Give object and image distances, type, size and magnification for object placed in front of spherical mirror.

Explanation

Concave mirror :
(i) Object position : (u = `infty`) Image position : at principal focus F
Image type : Real and inverted
Image size : Highly diminished
Magnification :m `lt lt ` -1

(i) Object position : Slight far from .C. `(infty gt u gt R)`
Image position : Between F and C
Image type : Real and inverted
Image size : Diminished
Magnification :m `lt`-1

(iii) Object position : At .C. (u = 2f)
Image position : At .C.
Image type : Real and inverted
Image size : Same as of object
Magnification : m = -1

(iv) Object position : Between .C. and .F. (f `lt` u `lt` 2f)
Image position : Far from .C.
Image type : Real and inverted
Image size : Magnified
Magnification : m `gt` -1

(v) Object position : At .F. (u = f )
Image position : At `infty`
Image type : Real and inverted
Image size : Highly magnified
Magnification : m `gt gt` -1

(vi) Object position : Between F and P (0 `gt` u `gt` f)
Image position : Behind mirror
Image type : Virtual and erect
Image size : Magnified
Magnification : m `gt` +1
Convex mirror :
(vii) Object position : At `infty` (u =`infty`)
Image position : At F
Image type : Virtual and erect
Image size : Highly diminished
Magnification : m `lt lt `+1

(viii) Object position : At any distance on axis
Image position : Between P and F
Image type : Virtual and erect
Image size : Diminished
Magnification : m `lt`+1
