Electromagnetic Radiation

4. Volt EV most convent energy unit for atoms and visible light.
5. produced by more or less room temperature objects. Used by the military to see in the dark.
7. combination of two protons and two neutrons, He4 nucleus.
10. produced by radios.
12. electrons that come from nuclear events.
13. Antimatter electrons, used for detecting cancer.
14. Usually come from electrons in very hot object, not enough energy to go though skin but photons have enough energy to cause skin cancer and eye damage.
17. 10^-9m, nm

1. 1/10nm
2. shortest, but highest frequency radio waves.
3. produced alpha, beta, gamma, and positrons.
6. hxf hxv
8. Smallest of EMR. Energy is so high they tend to go through things breaking up millions of molecules as they go.
9. elementary particle, force carrier for electromagnetic force. The quantum of light and all other forms of electromagnetic radiation.
11. produced by accelerating charges, usually electrons. Much like Gamma Rays but less. Used in hospital, produced by machines.
15. if we can see it, it is?
16. Diameter 0.2nm, or about two angstroms.
