The Early Workers in Spectroscopy (Fraunhofer with the Solar Spectrum;Bunsen

question 6

Multiple Choice

The early workers in spectroscopy (Fraunhofer with the solar spectrum;Bunsen and Kirchhoff with laboratory spectra) discovered what very significant fact about the spectra produced by hot gases,such as elements heated in a flame?

• A) The higher the temperature,the greater the proportion of red in the emitted spectral lines.
• B) They produce their own characteristic pattern of spectral lines,which remain fixed as the temperature increases.
• C) They emit spectral lines that move continuously toward the blue end of the spectrum as the gas temperature increases.
• D) They produce the same set of spectral lines and are hence indistinguishable.
