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