The image is at infinity in that case.

Why is it infinity?
Answered by

Because the optics rule is:
1/do + 1/di = 1/f
Since do = f, the focal length,
1/di = 0
That can only happen if the image distance di is infinity.
1/do + 1/di = 1/f
Since do = f, the focal length,
1/di = 0
That can only happen if the image distance di is infinity.
