Question 26
Activity 6.2.1: Refraction effects
Effect 2: Broken pencil in water
Pour water into a transparent drinking glass until it is about three-quarters full.
Place a pencil into the glass so it is resting at an angle.
View the glass and pencil from the side.
The pencil appears to be broken at the surface of the water.
Can you use a ray diagram to explain why? You need to think about how light travels from the pencil, through the water and out through the side of the glass.
