Slide 11

For a real object between f and the mirror, a virtual image is formed behind the mirror. The position of the image is found by tracing the reflected rays back behind the mirror to where they meet. The image is upright and larger than the object.

For a real object close to the mirror but outside of the center of curvature, the real image is formed between C and f. The image is inverted and smaller than the object.

For a real object between C and f, a real image is formed outside of C. The image is inverted and larger than the object.

For a real object between C and f, a real image is formed outside of C. The image is inverted and larger than the object.

For a real object close to the mirror but outside of the center of curvature, the real image is formed between C and f. The image is inverted and smaller than the object.

For a real object between C and f, a real image is formed outside of C. The image is inverted and larger than the object.

For a real object at C, the real image is formed at C. The image is inverted and the same size as the object.

For a real object at C, the real image is formed at C. The image is inverted and the same size as the object.

For a real object close to the mirror but outside of the center of curvature, the real image is formed between C and f. The image is inverted and smaller than the object.

Slide 14

For a real object at f, no image is formed. The reflected rays are parallel and never converge.

For a real object at f, no image is formed. The reflected rays are parallel and never converge.

What size image is formed if the real object is placed at the focal point f?
