The Emission Spectra of Various Light Sources

The fluorescent light gave the alike(p) breadth of spectrum as incandescent light, but the intensities were much smaller. With the atomic number 10 light, ???? CANNOT READ YOUR FAX

2. Bohr's atomic model was based on the fact that when matter is heated, it gives off light (Carpi, 2005). Bohr knew that when pure elements were excited by electricity or heat, they gave off distinct colors. For instance, when an electric on-going is passed through a tube containing neon gas, a rosy color is seen. When light from an excited element is passed through a prism, alone spectral lines are seen, which are characteristic for that element. Bohr believed that line spectra showed that atoms could not emit energy continuously but only in discrete quantities. He suggested that since the light was due to the action of electrons, therefore electrons could only move in precise steps, and he proposed that they occupy specific energy levels. Excited electrons jump to some other level. When they fall back to the lower level, quanta of light are emitted as specific wavelengths

3. The continuous spectra observed in this experiment from the vary light sources are not as sharply defined as the bright line spectra observed in the science laboratory and not as some spectral lines were seen.

This is because diffraction glasses and the homosexual eye were used and not a precision spectrophotometer. around 1860, the Scottish physicist Maxwell showed that two kinds of color existed, depending on whether

5. The electrons in the different light sources absorbed electromagnetic energy and emitted light energy.
