Quiz 3.1

1. Electric and magnetic field 2. 300,000 km/s 3. A beam of light shines on some substances, it causes electrons in the substances to move. If light didn't have any of the properties of a stream of particles, this movement of electrons won't occur. 4. Polarizing filter allows only waves of light that vibrate in 1 direction to pass through. If 2 polarizing filters are placed so that 1 is rotated 90 degrees, no light will pass through. 5. electromagnetic radiation 6. photoelectric effect 7. photon 8. polarized light 9. electromagnetic wave

Study Guide 2. 8 minutes 4. consist of changing electric and magnetic fields 5. light sometimes act as a wave 16. False- 90 24. Photo electric effects indicates that light sometimes acts like a stream of particles. Effect happens when light shines on a certain types of substances. Light causes electrons in substances to move or knock electrons out of the substance.
