WebAs shown in Figure 3b–d, the fluorescence Em peak near 685 nm and 710 nm was not detected under the high effective chlorine concentrations, suggesting that the light energy transfer process suffered serious damage under the NaClO treatments. However, the peak of fluorescence Em spectrum appeared near 585 nm. The electromagnetic spectrum is the range of frequencies ... Passing white light through a prism splits it up into the several colours of light observed in the visible spectrum between 400 nm and 780 nm. If radiation having a frequency in the visible region of the EM spectrum reflects off an object, say, ...
