Taking It In: The Effect of Varying Wavelengths of Visible Light on Oxygen Production in Hemigraphis alternata

Katelyn Robinson, Cade Morris, Jenica Lee, Michael Cobbs


Different plants grow better under different wavelengths of light. The reason the plants grow better under different light is due to the absorbency of the leaves (French, 2014). With ample tests having been run on the absorption of different wavelengths of light, the group decided that an additional test focusing on the effects of different wavelengths of light on Hemigraphis alternata. There is a direct relation between the rates of photosynthesis and absorption (French, 2014). The leaves’ oxygen production was tested under different color lights. This experiment provides additional information in the essential information of light absorption.
