RAY TRACING FOR A CONCAVE MIRROR
Ray 1. This ray is initially parallel to the principal axis and, therefore, passes through the focal point F after reflection from the mirror.
Ray 2. This ray passes through the focal point F and is reflected parallel to the principal axis. Ray 2 is analogous to Ray 1, except that the reflected, rather than the incident, ray is parallel to the principal axis.
Ray 3. This ray travels along a line that passes through the center of curvature C and follows a radius of the spherical mirror; as a result, the ray strikes the mirror perpendicularly and reflects back on itself.
RAY TRACING FOR A CONVEX MIRROR
Ray 1. This ray is initially parallel to the principal axis and, therefore, appears to originate from the focal point F after reflection from the mirror.

Ray 2. This ray heads toward F, emerging parallel to the principal axis after reflection. Ray 2 is analogous to Ray 1, except that the reflected, rather than the incident, ray is parallel to the principal axis.
Ray 3. This ray travels toward the center of curvature C; as a result, the ray strikes the mirror perpendicularly and reflects back on itself.
