(e) Light intensity can be calculated using the inverse square law:
1/2
d²
10.
Where / is light intensity and d is the distance of the pondweed from the light source.
The student placed the pondweed at 5, 10 and 20 cm from the light source.
Explain how light intensity changes as the distance of the pondweed from the light source is
doubled.
You must include calculations in your answer.
