Document Summary
As electrons relax back down, each energy level difference is discrete or quantized, and corresponds to a single wavelength. All these discrete wavelengths would be mixed into one colour, but if we allow this light to pass through a narrow slit and through a prism, we can separate out all of the different wavelengths (color) We would get an atomic emission spectrum. Atomic absorption spectrum, we see all wavelengths of light except those that are being absorbed, which appear as black bands in the spectrum. When you collect the emission and absorption spectrum for the same sample, the lines correspond to the gaps. Not limited to just atoms but also apply to molecules. Allows us to identify presence of different molecules in samples since each atom or molecules has a unit set of bands. 9. 109 x 10^-31 kg = mass of electron (m) Mass (m) x speed (u) also equals momentum (p)
