• - It is a phenomenon wherein the left side of the object appears to be on the right side of the reflecting image and vice versa

• - ratio of the image dimension to the object dimension

Two types of curved mirror

• - A line passing through the exact center of the concave mirror.

• Vertex

• Center of curvature

• Principal axis

• Focal point

• - midway between the vertex and the center of curvature

• Vertex

• Principal axis

• Focal point

• - the point in the center of the spehere from which the mirror was sliced

• Vertex
