center of curvature

center of the imaginary sphere where mirror is cut

principal axis

straight line passing through c and p, main axis of the mirror

focus

point where reflected rays or extensions appear to meet, between c and p

focal length

distance between the pole and the focus

aperture

width of the reflecting surface of the mirror

object beyond c

image between c and f, inverted, size reduced

object at c

image at c, inverted, size same

object at f

no image

location of object

anywhere u put the object

location of image

behind the mirror, between pole and f
