Ideas in this flowchart

• Image formation by an optical system
• An object provides the source of light rays.
• The optical element changes the direction of the rays.
• Incident rays travel from the object toward the optical element.
• The rays are refracted or reflected by the optical element.
• The outgoing rays determine the image position.
• The image is formed where the outgoing rays meet or appear to originate.
• The image has specific characteristics such as orientation, size, and type.
