  1. What two fields did James Maxwell join together?
    1. Briefly describe the Electromagnet Theory.
      1. Electricity+Magnetism
      2. Light=oscillating electromagnetic fields
  2. What phenomenon did Thomas Edison call the Edison Effect? (page 8)
    1. What causes this Effect?
      1. Edison noticed that there were splotches in lightbulb
      2. Cathode Ray Particles
  3. What is Photosensitivity? (page 8)
    1. What are the measurable results of this phenomenon?
      1. Photosensitivity is when wavelengths of light cause changes in energy levels.
  4. What did Sir Joseph John Thomson discover?
    1. What is an electron?
      1. electron=cathode ray particle
    2. Explain the Plum-Pudding model of the atom (pages 8-9)
      1. atom=random mixture of electrons and protons
  5. What experiment did Ernest Rutherford perform with the gold foil?
    1. Explain the Nuclear model of the atom.
      1. Rutherford found that when he shot small particles at atoms, it bounced off of small areas of it
      2. Found nucleus with protons and neutrons, which serve as "nuclear glue"
  6. Who was Max Planck?
    1. What is the concept of a quanta and how does it apply to the realm of subatomic particles?
      1. Light packaged in discrete quantities
      2. Prevents matter from releasing unlimited levels of light
  7. What led Einstein to propose the photoelectric effect?
    1. What are the measurable results of this phenomenon?
      1. Noticed that things change to a certain color when they reach a certain level of energy.
      2. Must be rejecting extra.
      3. Absorbs energy and releases light
