In order of increasing wavelength, the color spectrum ranges in the order of blue-yellow-orange-red. Which of the following statements is true about the relationship between wavelength and photosynthesis?

Question

Quizplus · Accepted Answer

When wavelength increases, photosynthesis decreases, then increases. Photosynthesis is stimulated most by red and blue light, which exist on opposite ends of the wavelength spectrum
Key Takeaway: The wavelength of visible light ranges from about 380-750 nm. Blue light is on the lower end of the scale, and red light on the higher end of the scale. Yellow and orange are in the middle. Since the data indicate that yellow and orange have the smallest effect on photosynthesis, the effect of light on photosynthesis decreases and increases as the wavelength of light increases.
