Mirror Equation
Object and Image Position:
For spherical mirrors,

,
where
p
is the distance from the
vertex to the
object
,
i
is the
distance from the vertex to the
image
, and
f
is the
focal length
.
Focal Length:
For spherical mirrors the focal
length,
f
, is onehalf of the radius
of curvature,
R
, as follows:
f = R/2
.
Magnification:
The

where the magnitude of the magnification is the ratio of the height of the
image,
