- A piece of paper with an arrow drawn on it.
- 1 glass
- 1 glass of water.
WHAT TO DO
Draw an arrow on the piece of paper.
Then put the empty glass in front of the piece of paper with the arrow on it.
Finally pour water into the glass and watch in amazement as the arrow changes its direction!
WHY THIS HAPPENS?
In the experiment light traveled from the air, through the glass, through the water, through the back of the glass, and then back through the air, before hitting the arrow.
When the light passes from one material, into another, it bends or refracts i.e. refraction of light.
