Principle
In this experiment you will develop a rule about how the light is attenuated when it passes through coloured liquids.
Benefits
Tasks
How is light attenuated by liquids? If light passes through a substance, irrespective of wether it is solid or liquid, it is, in general, less intense when it leaves than when it entered.
