Sunlight peaks in the blue spectrum at 475 nanometers (nm). This is a shorter wavelength than red light and is used by both plants and algae. As light passes through water the intensity decreases. The shorter wavelength blue light penetrates water better and more quickly than red, which is slower and absorbed more quickly. Chlorophyll, the photosynthetic pigment used by plants traps blue and red light but is more efficient with red light at 650 – 675nm. Blue is used at the same rate as red because it is more available for reasons mentioned above.
For green plants the lighting peaks that are most important:
Chlorophyll-a: 430nm/662nm
Chlorophyll-b: 453nm/642nm
Carotenoids: 449nm/475nm
Red pigmented plants use more light in the blue area of the spectrum.
