Mean wavelength of sodium light

WebFeb 28, 2024 · Abstract All previous reviews of research on light-emitting diodes (LEDs) have been focused on how different light spectra generally influence plant yield and quality. There are no or almost no reviews on the effect of spectra on sugars or pigment concentration, or yield and growth etc. The role of visible light in food production, as in agriculture and … WebMay 10, 2024 · We know absorption spectrum of sodium is near 595 nm wavelength which is in the region of yellow colored light. Why doesn't sodium (valence electrons) absorb EM wave of wavelength smaller than the wavelength 595 nm? I know that it cannot absorb wave of energy less than the two energy levels, but it can absorb more than that.
