Answer

Brief Explanations:

  1. Electromagnetic waves are made of photons and can travel through a vacuum, not just matter.
  2. Like - charged particles repel, opposite - charged particles attract.
  3. The frequency and wavelength of a wave are inversely proportional.
  4. The speed of a wave depends on the medium it travels through.
  5. The energy of an electromagnetic wave comes from vibrating electrical charges.
  6. Hertz (Hz) is the unit of frequency, and 1 Hz means 1 vibration per second.
  7. Light can behave as a particle called a photon, not a neutron.
  8. Electromagnetic waves travel at the speed of light (300,000 km/s) in a vacuum.
