![A horizontal line represents the principal axis. On the right, a concave circular arc curves inward toward the left, representing a concave mirror. Along the axis to the left of the mirror, two vertical tick marks are labeled F and C, where F is located at a distance f from the mirror and C is located at a distance 2f from the mirror. Three vertical upward-pointing arrows of equal height stand on the principal axis: arrow 1 is located at 3f to the left of the mirror, arrow 2 is located at 1.5f between C and F, and arrow 3 is located at 0.5f between F and the mirror. Arrow 1 is labeled 1, arrow 2 is labeled 2, and arrow 3 is labeled 3. No other labels, rays, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1790596700-3SbDys.jpg)
