A candle light experiment

Experiment 2:

How does the shadow change if you move the candle closer towards the object?

First, postulate an assumption. Think about how you can check your assumption in an experiment. Do your experiment. Observe and compare the results with your assumption. What can you say about that?

a) The shadow is now larger and wider.

b) The shadow is now longer and thinner.

c) The shadow does not change.
