Summarizing Image Formation by Mirrors
Image Formation by Mirrors Summary
- The characteristics of an image formed by a flat mirror are: (a) The image and object are the same distance from the mirror, (b) The image is a virtual image, and (c) The image is situated behind the mirror.
- Image length is half the radius of curvature.
\(f=\cfrac{R}{2}\)
- A convex mirror is a diverging mirror and forms only one type of image, namely a virtual image.
Glossary
converging mirror
a concave mirror in which light rays that strike it parallel to its axis converge at one or more points along the axis
diverging mirror
a convex mirror in which light rays that strike it parallel to its axis bend away (diverge) from its axis
law of reflection
angle of reflection equals the angle of incidence
