What location does the image approach as it gets farther away from the mirror?
Note the characteristics of an image formed by a concave, spherical mirror. When the object is outside the focal point, the image is inverted and real; at the focal point, the image is formed at infinity; inside the focal point, the image is upright and virtual. Question What location does the image approach as the object gets arbitrarily far away from the mirror? (Select all that apply.) The mirror itself. The radius of curvature of the mirror. The focal point. Half the radius of the mirror. Infinity.

- yup
- As the object approaches infinity, the image approaches the focal point. This is, in fact, the definition of the focal point.
- It might be that this question is just over my head, but it's not clear to me what we're talking about. I became lost when I asked myself, is he talking about a subject with an eyeball viewing a spherical mirror who's position does not move?... in which case the focal point, the image, and it's inverse or otherwise would make sense to me... But I wasn't certain about the movement of the object in relation to the viewer... so I can't answer? Does that mean I'm an idiot? I have no idea.
