4. Angle of incidence Angle of Reflection Normal Mirror Line The Angle of Incidence is equal to the Angle of Reflection

6. Plane Mirror A virtual image is created behind the mirror! A mirror with a perfectly flat surface This diagram shows how an image is created. The brain perceives an image straight ahead (behind the mirror).
