WebMost chlorophyll systems use a light-emitting diode (LED) as the source of the irradiating light that has a peak wavelength of approximately 470 nm. LEDs with this specification produce radiation in the blue region of the visible spectrum. On irradiation WebJan 11, 2024 · All light sources used in this experiment were LED lights (Fujian Talos Technology Co., Ltd., Fuzhou, Fujian, China). The wavelengths of all LED lights (460 nm for the peak wavelength of blue light and 660 nm for the peak wavelength of red light) were tested with a light meter (LI-250A, LI-COR Biosciences Co., Lincoln, NE, USA).

WebIn order to determine the health of plants or algae we first have to measure their chlorophyll concentration which is where the spectrophotometer comes in. The spectrophotometer uses light emitting diodes (LEDs) with a dominant wavelength peak of … WebA) Green and yellow wavelengths inhibit the absorption of red and blue wavelengths. B) Oxygen given off during photosynthesis interferes with the absorption of light. C) Other pigments absorb light in addition to chlorophyll a. D) Aerobic bacteria take up oxygen, which changes the measurement of the rate of photosynthesis.
WebApr 11, 2024 · It can be observed that a prominent absorption peak occurred between 662 and 666 nm in wavelength. These absorption peaks are the signature indication of the presence of chlorophyll-a [ 35 ]. In addition, the peaks for both protic extracts were seen as more intense at long wavelengths compared to other solvents.
