Across
  1. 2. Unlike mechanical waves, EM waves are able to travel through this
  2. 3. This acronym helps remind us of the colors that make up the visible spectrum
  3. 5. The color with the shortest wavelength in the visible spectrum
  4. 6. This region of the EM spectrum can penetrate through many objects which is why it is useful for creating images
  5. 7. Since EM waves travel at right angles we consider them this type of wave
  6. 10. Found by multiplying wavelength and frequency of a wave
  7. 12. The color of the visible spectrum with the second longest wavelength
  8. 13. This region falls between visible light and x-rays and can be detected by insects
  9. 14. These waves have the shortest wavelengths, highest frequencies, and most energy
  10. 15. Infrared radiation has the third lowest on the spectrum
  11. 16. The wavelengths that our eyes can detect are so small that they are measured in this unit
  12. 18. All EM waves have this in common
Down
  1. 1. These waves have the least energy and are used to broadcast TV shows
  2. 4. Felt as heat but also used in some electronics
  3. 5. This small portion of the EMS is the only region with wavelengths that our eyes can detect
  4. 8. Used in many forms of communication that we rely on every day
  5. 9. Waves with a high frequency have a short one of these
  6. 11. Gamma rays have the highest amount of this on the spectrum
  7. 17. A wave carrying a lot of energy will have a larger one of these
