3.2 Atomic Spectra

Question 1

A set of dark lines in the otherwise continuous solar spectrum.

Answer 1

Fraunhofer Lines

Question 2

These scientists discovered that the light emitted by elements vaporized in the transparent flame of a gas burner produced spectra that were opposite of Frauhofer’s.

Answer 2

Robert Bunsen and Gustav Kirchoff

Question 3

Shows us that atoms of each element emit light of a characteristic color.

Answer 3

Atomic Spectroscopy

Question 4

A series of bright lines that can separate light(black background & color lines)

Answer 4

Emission Spectrum

Question 5

Characteristic patterns of bright lines are produced when atoms are vaporized in high-temperature flames or electrical discharges.

Answer 5

Atomic Emission Spectra

Question 6

Characteristic patterns of dark lines produced when an external source of radiation passes through free gaseous atoms.

Answer 6

Atomic absorption spectra

Question 7

This is not a line spectrum, but rather a continuous spectrum.

Answer 7

White light

Question 8

Match the atomic emission bright lines of some elements with the corresponding Fraunhofer dark lines.
