  • Background: Introduction to Spectroscopy - Imagine the Universe!
    Background: Introduction to Spectroscopy Introduction to Spectroscopy Spectroscopy is a complex art - but it can be very useful in helping scientists understand how an object like a black hole , neutron star , or active galaxy is producing light , how fast it is moving, and even what elements it is made of
  • Imagine the Universe! Spectra
    In a star, there are many elements present We can tell which ones are there by looking at the spectrum of the star The science of spectroscopy is quite sophisticated From spectral lines astronomers can determine not only the element, but the temperature and density of that element in the star
  • X-ray Spectroscopy - Imagine the Universe!
    Background: Introduction to Spectroscopy - Everything you ever wanted to know about spectroscopy but were afraid to ask! Activity: Graphing Spectra - Practice drawing graphs of spectra, and understanding the different ways spectra can be represented, as well as what each representation can tell us
  • Imagine the Universe!
    With that discovery, scientists had the means to determine the chemical composition of stars through spectroscopy Stars aren't the only objects for which we can identify chemical elements Any spectrum from any object allows us to look for the signatures of elements This includes nebula, supernova remnants and galaxies
  • Supernova Chemistry Lesson Plan - Imagine the Universe!
    Atomic spectroscopy is an extremely important tool for scientists Because the electron patterns around every kind of atom are unique, and because these electrons interact with light in different ways because of their different positions, you can determine what kinds of atoms are present in a substance by the kind of light absorbed or emitted
  • X-ray Spectroscopy Lesson Plan - Imagine the Universe!
    Students will read and write about the spectroscopy of stars and supernova remnants, as well as understand their relevance and impact on human life Students will also learn about cutting edge technology that will help us to build better instruments with which to study the Universe
  • Imagine the Universe: Spectral Analysis Activities
    These activities were designed to aid student understanding of spectral analysis, what the patterns mean, how elements are involved, and how this relates to stars
  • X-ray Spectroscopy and the Chemistry of Supernova Remnants Selected . . .
    X-ray Spectroscopy and the Chemistry of Supernova Remnants Selected Worksheet Keys Calculation Investigation – Students learn about unit analysis by converting energies to wavelengths to frequencies Calculate the Energy! – Students will calculate the energy differences in different energy states of the Bohr atom of Hydrogen
  • Wavelength, Frequency, and Energy - Imagine the Universe!
    Regions of the Electromagnetic Spectrum Listed below are the approximate wavelength, frequency, and energy limits
  • Activity: Flame Test - Imagine the Universe!
    Recalling the characteristics of both atoms and light, the flame test is a great way to physically demonstrate some of the more abstract ideas discussed in the background sections on Atoms and Light Energy and Spectroscopy
