Document Summary

In the example of a real image, you would only see the image clearly if you were further from the mirror than the image (so your eye received diverging rays) Concave shapes can also be used for other waves (sound mirror) Convex mirrors can also use the mirror equation. Careful with the sings of distances: f is negative in this case (but the rest of our sign convention is unchanged) A convex right-hand rear view mirror on a car. You look into a shiny christmas tree ball (diameter 9. 0 cm) from. With ray tracing, we can draw the position of the image of an arbitrary object, with rules much the same as those for spherical mirrored surfaces (see last lectures) Rays parallel to the optic axis are refracted through the focal point. Rays through the second focal point finish. We can do the same for diverging lens. For a lens composed of two spherical surfaces, the lensmaker"s equation is: insert.
