Spherical-Mirror

Ray tracing for spherical mirrors. Note that real and virtual rays are not distinguished here.

Move D to move the object and to change the size of the object. Move B to change the focal length of the mirror.

What happens when you move D below the horizontal axis?

What happens as you change the size of the object relative to the size of the mirror?

What happens when you move the object through the center of curvature (the origin here)? What about moving through the focal point? What about moving to the other side of the mirror.
