Interpreting Spectra Worksheet

Interpreting Spectra

Read each question carefully and provide clear, concise answers. Show all your work where applicable. Refer to the provided diagrams and information to help you answer the questions.

1. Which type of spectrum is produced when light from a hot, dense source passes through a cooler, less dense gas?

2. What information can be determined about a star by analyzing its absorption spectrum?

1. An emission spectrum consists of bright lines on a dark background, indicating that specific   of light are being emitted by the source.

2. The Doppler effect observable in spectral lines can be used to determine the   motion of celestial objects.

3. Each element has a unique spectral fingerprint because of its distinct electron   levels.

1. Briefly explain the difference between a continuous spectrum and an emission spectrum.

1. The presence of dark lines in an absorption spectrum indicates that those specific wavelengths of light have been absorbed by the intervening gas.

2. A hot, dense object will produce a line emission spectrum.
