5 True/False Questions

1. supernova → the rainbow that you see when looking at a spectroscope

   True        False

2. types of galaxies → are the explosion of a dying star. Iron begins to absorb energy, soon this energy is released and explodes

   True        False

3. spectrum → the rainbow that you see when looking at a spectroscope

   True        False

4. wavelenghth → the length from crest to crest in a wave

   True        False

5. nebula → apparent change in the position of a star in the sky. Not because it has moved but because the Earths change in position as it moves around the sun.

   True        False
