Problem Solving: Spherical Mirrors
1. Draw a ray diagram; the image is where the rays
intersect.
2. Apply the mirror and magnification equations.
3. Sign conventions: if the object, image, or focal point
is on the reflective side of the mirror, its distance is
positive, and negative otherwise. Magnification is
positive if image is upright, negative otherwise.
4. Check that your solution agrees with the ray diagram.
