REFLECTION and REFRACTION
For a flat mirror, the image and
object distances are the same, the magnification is 1.0, and the
image is virtual (no light rays are brought to a focus at the
point apparently occupied by the image). Some
solved examples involving reflection.
REFRACTION OF LIGHT
Snell's Law was unpublished
during his lifetime, and was recovered by Huygens
in 1703. A version of the law perhaps was known to Ibn Sahl in
984; at least, he may have used a similar idea in discussing
images formed by lenses.
