why would you not use green light and white light if you wanted to determine the dependence of specific color wavelengths on the rate of photosynthesis?
Given our understanding of the situation, we can confirm that the use of green or white light would not be ideal for the experiment at hand because it will not yield any useful information.
In this experiment, we wish to determine the dependence of specific color wavelengths on the rate of photosynthesis. The use of white light for this experiment will defeat the purpose, given that white is the naturally occurring color of light and the available data on this is vast.
Furthermore, we would not use green colored light because it will not be effective. The effectiveness of the color of light that we decide to use will be based on the absorption rate of the light at a cellular level. Green light is known to not be well absorbed by the chlorophyll of plants and therefore will not be useful.
