Drawing a Reflected Image

When drawing a reflected image, you must always follow the following instructions:

Always use a ruler and pencil

Always use a ruler and pencil

  • Light travels in straight lines after all.
Use arrows to show direction

Use arrows to show direction

  • Light rays must have an arrow on the light ray.
  • The arrow shows the direction of the light.
Draw a normal

Draw a normal

  • A normal line is drawn at 90° from the mirror.
  • The normal line is normally dotted.
  • The incident ray hits the mirror at the normal.
  • The reflected ray reflects off the mirror.
Remember the law of reflection!

Remember the law of reflection!

  • The law of reflection.
  • The angle of incidence is between the incident ray and the normal.
  • The angle of reflection is between the reflected ray and the normal.
  • The two angles are equal.

Test yourself on Drawing a Reflected Image

  • How should the normal line be drawn in a reflection diagram?

  • Which of these are true of reflection diagrams?

  • A ray of light hits a mirror. If the angle of incidence is increased, what happens to the angle of reflection?
