The shape of a mirror can affect what you see.
- If you look into a convex mirror (one that bends out), you will see yourself tall and thin.
- If you look into a concave mirror (one that bends in), you will see yourself short and wide.
If you want to see a normal image of yourself, look into a flat mirror.
An image seen in a mirror is due to the reflection of light in the mirror.
The perpendicular line to the mirror is called the normal.
The angle of incidence is the angle between the incident ray and the normal.
The angle of reflection is the angle between the reflected ray and the normal.
Measurements show that for any light ray reflected by a mirror:
- The angle of incidence = angle of reflection
