Across
- 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
- 5. a type of radiant energy that is invisible to the eyes- only felt in form of heat
- 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
- 9. Ray penetrating electromagnetic radiation of a kind arising from the radioactive decay of atomic nuclei
- 10. form of electromagnetic radiation with wavelength shorter than that of visible light, but longer than X-rays-present in sunlight
Down
- 1. ray high-energy particles or clusters of particles that move through space at nearly the speed of light
- 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
- 4. an electromagnetic wave of high energy and very short wavelength, which is able to pass through many materials opaque to light
- 6. technology of signaling and communicating using radio waves
- 8. Wave an electromagnetic wave of a frequency between about 104 and 1011 or 1012 Hz, as used for long-distance communication
- 11. electromagnetic radiation that can be perceived by the human eye
