Reef Chemistry Question of the Day #227
You are interested in knowing how much UV is penetrating your reef aquarium. You do an experiment and determine that at a particular wavelength, 31.767% of the UV is removed after the light passes through 6 inches of your aquarium water.
If that same wavelength passed through 18 inches of the same water, what fraction of the UV would remain?
A. 0.000%
B. 4.699%
C. 15.239%
D. 31.767%
E. 68.231%
Good luck!
