Across
  1. 4. The range of frequencies over which electromagnetic radiation extends (from radio waves to gamma waves)
  2. 7. An material that does not allow light to pass through it.
  3. 8. Wavelengths of invisible electromagnetic radiation that are slightly longer than those of visible red light.
  4. 10. A material that allows light of certain wavelengths to pass through it without significant scattering such that images can be observed.
  5. 11. The smallest energy packet of light or other electromagnetic radiation of a given wavelength that can exist.
  6. 12. To separate and move in different directions, scatter. To separate white light into components of different wavelengths (different colors).
  7. 13. The smallest energy packet that can exist.
Down
  1. 1. Energy (contained in electric and magnetic fields) that can be transmitted and may be thought of as having properties of both waves and particles (photons).
  2. 2. A disturbance that may occur when waves (including light waves) travel in the same or different directions in the same space.
  3. 3. Wavelengths of invisible electromagnetic radiation that are slightly shorter than those of visible violet light.
  4. 5. To cast back from a surface (as with thermal energy, light, and waves).
  5. 6. To change direction or bend from the original path, as with light waves.
  6. 9. A material that allows light to pass through it, but scatters the light such that images cannot be observed.
