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. A spectrum is simply a chart or a graph that shows the intensity of light being emitted over a range of energies. Spectra can be produced for any energy of ...
Spectroscopy can be very useful in helping scientists understand how an object like a black hole, neutron star, or active galaxy produces light, how fast it is moving, and what elements it is composed of. Spectra can be produced for any energy of light, from low-energy radio waves to very high-energy gamma rays.
Advanced Basic Spectral Analysis 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. The lines can also tell us about the magnetic field of the star ...
Supernova Chemistry Suggested grade levels: 9-12 Estimated class time: 2-3 class periods Lesson plan by Jane Mahon and Ron Dodson of Hoover High School in Hoover, Alabama Summary This lesson gives the student an opportunity to identify elements by using spectroscopy and to relate this activity to astrophysics. Students will use spectrometers to measure the spectra of various light sources at ...
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. Each section has several pages of background material relevant to the associated activities and the lesson plan ...
