Pulling it Together
Let's look at the SNR spectrum again - note the emission lines. Using
a periodic table, can you identify which elements are present in this
supernova remnant?
Why is it hard to tell exactly what energy the photons being emitted
by magnesium are?
For more exercises relating to the spectra of supernovae, please visit our
Unit on Spectroscopy
at the Imagine the Universe! site, great for grades 9-12!
