Witryna16 mar 2024 · It is not possible to get purely monochromatic radiation using a dispersing element with a slit. Usually the sample has a slightly different molar absorptivity for each wavelength of radiation shining on it. The net effect is that the total absorbance added over all the different wavelengths is no longer linear with … WitrynaA laser is basically just a bunch of light waves that all have the same wavelength and are all lined up with one another. Suppose you place a card in front of the laser beam …
