This book presents the concepts of spectral analysis and the Doppler Effect to determine the composition and movement of stars.
After reading and interacting with this eBook, students should be able to:
• recognize that all stars produce a unique spectral pattern when viewed through a spectroscope;
• identify the three types of spectra;
• describe the conditions that produce each type of spectrum; and
• identify a red shift or a blue shift in the spectral pattern and conclude from that information if a star is moving towards or away from the viewer.
