Procedure: Part I: Fluorescent tube data and Hydrogen spectrum We will provide you spectra from gas discharge lamps, as it is impossible to make those lamps available to students in an online course. The understanding of spectra is foundational to many of the labs that follow, so it will be important for you to have an opportunity to study them. In this lab we will look only at visible light and try to figure out something about the patterns we see from different elements and how those patterns can be clues to other things we want to know. Through examining various wavelengths of light, ranging from visible light to radio waves to X-rays and everything between, astronomers can learn about the materials that make up stars, galaxies, and the space between them, can figure out distances and masses, temperature and pressure and even rotational speed, age of objects and of the universe.
Introduction: Light in all its forms is the primary tool in stellar and galactic astronomy. and more Astronomy Lab Reports in PDF only on Docsity!Atomic Spectra Lab Handout and Answer Sheet Your Name: Joseph Park Purpose: The purpose of this lab is to examine the atomic spectra from several light sources and understand how spectra can help identify a light’s source.
