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

Always use a ruler and pencil
- Light travels in straight lines after all.

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
- 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!
- 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.

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?
