- Drag the object back and forth in front of the mirror, and study the
- If you click your mouse at any point along a light ray, and then drag
the mouse cursor to the right along the ray, you can measure the angle
of that ray with respect to a line normal to the mirror. Do so, and
verify that the law of refection governs the behavior of each light
ray that strikes the mirror's surface.
- Do the rays that leave the top of the object, traveling in
different directions and reflecting off the mirror, ever come together again?
- Do those rays, having reflected from the mirror, appear to emanate
from the same point behind the mirror?
- Is this, then, a real or a virtual image?
- The mirror is located at x = 2.0 cm. Where are the object and image
located, relative to the mirror?
- How does the image height compare to the object's height?
- Is the image upright or inverted?
