  1. 3. Radiation including nuclear radiation, consists of subatomic particles or electromagnetic waves that have sufficient energy to ionize atoms or molecules by detaching electrons from them
  2. 5. a type of radiant energy that is invisible to the eyes- only felt in form of heat
  3. 7. Spectrum portion of the electromagnetic spectrum that is visible to the human eye. Electromagnetic radiation in this range of wavelengths is called visible light or simply light
  4. 9. Ray penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei
  5. 10. form of electromagnetic radiation with wavelength shorter than that of visible light, but longer than X-rays-present in sunlight
Down
  1. 1. ray high-energy particles or clusters of particles that move through space at nearly the speed of light
  2. 2. an electromagnetic wave with a wavelength in the range 0.001–0.3 m, shorter than that of a normal radio wave but longer than those of infrared radiation
  3. 4. an electromagnetic wave of high energy and very short wavelength, which is able to pass through many materials opaque to light
  4. 6. technology of signaling and communicating using radio waves
  5. 8. Wave an electromagnetic wave of a frequency between about 104 and 1011 or 1012 Hz, as used for long-distance communication
  6. 11. electromagnetic radiation that can be perceived by the human eye
