Emission spectra of the LCGD-AES The emission spectra of the LCGD-AES in blank (a) and 50 mg L− 1 Cu solution (b) are shown in Fig. 2. As shown in Fig. 2a, there are several lines and bands present in the spectra. The main lines and bands of excited species result from OH...
It helps to identify elements in the astronomical object by studying their spectra. Astronomers can measure the spectrum of light from a star to know the elements of the star. Each element emits light at a particular wavelength, therefore astronomers can find out what elements made up the stars...
