I need to calculate the intensity of a 10000 lux light source traveling through 3.3 cm of water. I have attempted to solve this using the equation I=Ioe-A where i is the intensity, Io is the initial intensity, A is the absorbance calculated as the water attenuation coefficient times the...

Homework Statement I am currently doing a biology honours project at university and have been stumped by a fairly basic physics hurdle. I need to know the equation to calculate the amount of light absorbed by water/unit depth. I have tried to find the equation all over but cannot find...
