Figure 11: Formation of an image in a plane mirror

Activity 5

Investigating the reflection of light

Materials: Plane mirror, table and pen

Procedure

1. Take a plane mirror and place it on the table, then look at
yourself in the mirror.

2. Take a pen and hold it in front of the mirror.

3. Record the results of your actions. What did you discover
from the observation you made?

When light rays hit smooth, shiny surface, they are reflected.
The reflection of light rays causes the formation of image of an

object or people in the mirror. For example, when you look in
the mirror, light from a light source bounces off your body to the
mirror. The mirror reflects the light back to your eyes, allowing
you to see your image.
