Answer:
:
Reflection of light: 1 Mark
Activity: 4 Marks
When light rays hit a highly polished smooth surface like a mirror, it bounces back to the same medium like a ball thrown against a wall. It is called the reflection of light.
Activity to show the reflection of light: Ask 3 of your friends to join this activity. In a dark room or in the night, ask one of your friends to hold the mirror in one corner of the room. You and your other friend stand anywhere in the room. Take a torch and direct beam of light to the mirror that your friend is holding. Adjust the direction of the torch so that some of the beam of light hits on your friend. This activity shows that the light you directed hits the mirror and bounces back to your friend.
