Understanding Emission and Absorption Spectra in Astronomy

On January 8 and 9, we will explore the characteristics of emission and absorption spectra, laying a foundation in basic spectroscopy. We'll discuss its significance in astronomy, emphasizing how astronomers use this tool to decipher the composition and behavior of distant celestial objects. The session will kick off with an engaging discussion on the applications of spectroscopy in astronomy. Essential vocabulary, including spectroscopy, spectroscope, and spectrograph, will also be covered to enhance understanding.

  1. Learning Target: Be able to describe the characteristics of emission and absorption spectra and understand basic spectroscopy and how it applies to Astronomy Kick off: How is spectroscopy used in astronomy? Vocabulary: Spectroscopy Spectroscope spectrograph Turn in Holiday Homework Check—bring me your logs Finish spectroscopy-notes and lab, turn in lab Reading pg. 77-81 then read the summary on pg 94 Answer review and discussion questions 1,2, and 3 in complete sentences. Describe Kirchoff’s laws. If time: Video on Telescopes Jan 8 and 9 Agenda
  2. Kirchoff’s law #1: Solids and liquids emit light of all wavelengths and are said to have a ________________________ of radiation. Kirchoff’s law 2 states that a __________________________________emits light whose emissions are characteristic of the gases chemical composition. Kirchoff’s third law states that a ______________________________leaves dark absorption lines. Radiation can be analyzed with an instrument known as a This is used in a spectroscope in place of a prism.
