I am to conduct a lab investigating how different wavelengths of light affects photosynthesis in Egeria pondweeds.
The idea is to put color filters on light bulbs and shine them on the pondweed in a sodium hydrogen carbonate solution. Then to measure the oxygen, I have an oxygen sensor which measures dissolved oxygen (mg/L).
Now, what I have a trouble with is if measuring the dissolved oxygen is the right way to measure the rate of photosynthesis depending on color of light? Will it work?
