P1.5.2 Reflection

P1.5.2 Reflection

1. The normal is the construction line perpendicular to the reflecting surface at the point of incidence

2. the image produced in a plane mirror is virtual

   • virtual image
     • an image, seen in a lens or a mirror, from which light rays appear to come from after being refracted by the lens or reflected by the mirror
     • can't be projected onto a screen
   • upright (the same way up as the object) and laterally inverted (back to front but not upside down)

3. the angle of incidence is greater than the angle of reflection

   • angle of incidence
     • angle between the incidence ray and the normal
   • angle between the reflected ray and the normal

4. real image

   • an image formed where light rays meet
   • like an image on a screen
