Convex and concave mirrors are sections of a whole spherical mirror. A concave mirror has a reflecting surface on the inner part of the mirror. Its center of curvature and focal point is located on the same side as the object, making its focal length positive. On the other hand, a convex...
The focal length is the distance from the mirror to the point where all light that bounces off of the mirror goes through. Concave mirrors have a positive focal length and convex mirrors have a negative focal length. Positive distances are ...
