(A) Three hundred fourteen subjects in total 151 (114 males, 37 females) SZ and 163 (117 males, 46 females) HC. While interaction with infrared light causes molecules to undergo vibrational transitions, the shorter wavelength, higher energy radiation in the UV (200-400 nm) and visible (400-700 nm) range of the electromagnetic spectrum causes many organic molecules to undergo electronic transitions. Beer’s Law or the Beer-Lambert Law Pierre Bouguer discovered that light transmission decreases with the thickness of a transparent sample in 1729. You know that the expression for the Beer-Lambert’s law can be written as follows. (6) Food coloring.
