How detailed are reflections in mirrors?

If you were to zoom in on a mirror, just how detailed could the reflection be? Would it get blurry and fuzzy like when you try to zoom in on a picture? Or could you zoom in far enough and see atoms? 

(this is all assuming you have a mirror with 100% reflectivity and a good enough camera or microscope to zoom on atoms)

For most practical purposes (looking at light and visible things) the answer is that the mirror is infinitely detailed, given your assumption that the mirror is flawless.

Hypothetically speaking, you couldn't zoom in to the mirror to the atomic scale, you'd end up looking at the atoms of the mirror. However, you could look into a mirror reflecting a magnifying lens which will show you atoms of the object you're interested in.

Of course you can't actually see atoms, they're too impossibly small. When taking about looking at atoms you're usually talking about electron microscopes of some kind, these machines use magnetic lenses to do the work done by glass in an optical microscope.
