Reflection
2
Target

• Draw ray diagrams to show the path of light as it
  bounces off mirrors.

3

• Light travels in waves.
• A light ray shows the direction the waves are
  moving.
• Light rays are perpendicular to the wave fronts.
• An object reflects light in all directions (so it
  is visible from all directions).

4
Reflection

• Law of Reflection The angle of incidence the
  angle of reflection.
• This applies to ALL mirrors.

5

• Optics study of how light behaves
• Light can be used to create images pictures of
  an object formed by mirrors lenses where
  parallel light rays come together (focal point)

6

• Ray diagrams show the path that several light
  rays travel and can be used
• For finding the focus
• To determine if image is magnified or reduced
• To see if the image is flipped over

7

• Mirrors reflect rays of light to change their
  direction.
• Incident ray comes from the object
• Reflected ray bounces off the mirror.

• The image depends on the distance of the object
  from the mirror.
• Outside the center of curvature (C)
