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?
Answer:
When studying the dependence of specific color wavelengths on the rate of photosynthesis, green light is not used because chlorophyll, the main pigment in plants responsible for photosynthesis, does not absorb green light efficiently. Instead, chlorophyll absorbs red and blue light most effectively. White light, which is a combination of all wavelengths, would not be ideal either because it contains green light that is not absorbed well by chlorophyll. To determine the specific effects of different color wavelengths on photosynthesis, it is essential to use lights of specific colors, such as red and blue, which are absorbed most effectively by chlorophyll. By using these specific colors, researchers can accurately study the effects of different wavelengths on the rate of photosynthesis without interference from inefficiently absorbed wavelengths like green light in the case of chlorophyll.
