Question
A student puts his pencil into an empty trough and observes the pencil from the position as indicated in
- What change will be observed in the appearance of the pencil when water is poured into the trough?
- Name the phenomenon which accounts for the above stated observation.
- Complete the diagram showing how the student’s eye sees the pencil through water.
Solution
- Part of the pencil that is immersed in water will look short and raised up.
- The phenomenon that is responsible for the above observation is the refraction of light.
- The required figure is
