Concave Mirror Cartesian Sign Convention
Concave Mirror Cartesian Sign Convention
A system for specifying the position of points and distances related to a concave mirror using a coordinate system. Positive distances are to the right and above the principal axis while negative are to the left and below. The pole is the origin.
Mirror Formula
Mirror Formula
1/v + 1/u = 1/f. This relates the image distance (v), object distance (u), and focal length (f) of a spherical mirror.
Object Distance (u)
Object Distance (u)
Distance from the pole of the mirror to the object.
Focal Length (f) - Concave Mirror
