What would your image look like if you stood close to a large:(a) convex mirror?(b) concave mirror?

(a) If we stand close to a large convex mirror, our image will be smaller than us.

Explanation

For an object placed close or within the focus (between the pole $P$ and the focus $F$, the image formed by a convex mirror is virtual and erect, smaller than the object (diminish), and behind the mirror.

(b) If we stand close to a large concave mirror, our image will be larger than us.

Explanation

For an object placed close or within the focus (between the pole $P$ and the focus $F$), the image formed by a concave mirror is virtual and erect, larger than the object (enlarged) and behind the mirror.
