An electron gun emitted electrons inside a glass tube onto phosphor atoms at the end of the glass tube, causing the phosphor atoms to light up. The electron gun scanned the screen many times per second, producing an image. . ULTRAVIOLET RADIATION SPECTRUM. UVA (Longwave Radiation). Range 320-400 nm.

Ultraviolet and visible light give rise to electronic excitations.. Spectroscopy of organic molecules is possible because the absorption of radiation is restricted to quanta having energies corresponding to specific molecular excitations:. Katie Crozier.

In populations or when comparing closely related species, one major objective is to identify variation among the samples. AKA, one of the main goals in genomics is to identify what genomic features make individuals/populations/species different.
