Reading assignment: 36.1-36.2

While decorating your Christmas tree you notice that you can see yourself in one of the spherical, reflective ornaments. Is your image real or virtual? How do you know?

Will a converging (concave) mirror ever produce a focused image at the focal point? If yes, when? If not, why not?

What does it mean for a mirror to have a large "radius of curvature"?
