If we use Mirror Formula:
1/f=1/v+1/u
Where f is focal length, u is object distance from pole and v is image distance from pole.
As f is infinity,
we get 1/f=0 1/v =1/u v =u
If m is magnification and h' is image size and h is object size,
we have m=-v/u =h'/h (- v=u) h'/h
=1 h'=h So height of image and height of object are equal.
1/f=1/v+1/u
Where f is focal length, u is object distance from pole and v is image distance from pole.
As f is infinity,
we get 1/f=0 1/v =1/u v =u
If m is magnification and h' is image size and h is object size,
we have m=-v/u =h'/h (- v=u) h'/h
=1 h'=h So height of image and height of object are equal.
