Angle of Incidence  ( i ) = Angle of reflection ( r )

3.16 Construct ray diagrams to illistrate the formation of a virtual image in a plane mirror

For plane mirrors, the image is…

• The same size as the object
• The same distance as the object from the mirror
• Virtual (not real)
• Upright
• Laterally Inverted
