How wavelength is measured
WebThe fluorescence properties of groundwaters percolating into four cave systems have been monitored over the period 1997-1998. Fluorescence was excited between 220 and 400 nm and the emission measured from 300 to 500 nm using a fluorescence spectrophotometer. Three fluorescence centres were observed one at the excitation-emission pair of 290-340 ... WebWavelength is the measured distance between two identical points on two back-to-back waves. Thinking back to our ocean example, to measure the wavelength we would …
