Types of Spectra

• What is spectroscopy?
• What is a spectrum?
• What is a continuous spectrum?
• What is an emission line spectrum?
• What is an absorption spectrum?
• What type of objects emit a continuous spectrum of radiation?
• What kind of sources produce an emission line spectrum of radiation?
• From what type of sources do we get an absorption line spectrum of radiation?
• What type of spectrum do we get from a star like the Sun?

Temperature and Its Effects

• What is the lowest possible temperature that can be reached?
• How does the radiation from two identical solid objects
  with temperatures of 1000 K and 2000 K compare?
• What happens to the radiation emitted by an object if its temperature rises/decreases?
• Do regular objects in a room emit any kind of radiation?

Photons

• What evidence do we have that light is made of waves?
• What evidence do we have that light behaves like particles?
• Is light made of waves or particles? Is light a form of energy, a wave, or a particle?
• What is a photon?
• What happens to a photon's energy if we increase its frequency? Its wavelength?
• Which kind of photons have the highest/lowest energy?

Atoms and Molecules

• What happens inside an atom when a photon is absorbed?
• Why do different atoms emit waves of different wavelength?
• Can a molecule emit/absorb radiation in more ways than an atom?
• What kind of radiation do we normally use to identify molecules?

And Astronomy

• What properties of a star can we determine from its spectrum?
• Can any type of spectrum be used to identify the substance it came from?
• How do we find the temperature of a star from its spectrum?
• How do we find a star's radial velocity from its spectrum?
