Electromagnetic Radiation
by Andrew Fischenberg
1. Scattering-When a waves collides with something to change its path
1.1. New node
1.1.1. New node
2. Opaque-the degree to which light is blocked
3. Translucent-Allows light to pass through diffusely.
4. Diffraction-When a waves collides with something
5. EMR Spectrum-The range of all possible frequencies in Electromagnetic radiation
5.1. Band/Frequecies and Examples
5.1.1. 10^3-Radio
5.1.2. 10^-2-Microwave
5.1.3. 10^-5-infrared
5.1.4. .5x10^-5-Visible
5.1.5. 10^-8-Ultraviolet
5.1.6. 10^-10-Xray
5.1.7. 10^-12 Gamma Ray
6. Representations
6.1. Wave-Example-Ocean Wave
6.2. Ray-idealized narrow beam of light
6.3. Particle-matter that makes up the wave
6.4. Wave front-Line of points having the same phase
6.5. Wave packet-A short "burst" of wave that travels as a unit
7. Dispersion-Wave is not uniform, becomes frequency dependent
8. Interference-Occurs when a new wave patter is created by the collision of two or more waves
9. Absorption-The way in which energy is taken up by other matter
10. Polarization-Orientation of the waves electrical field at its oscillation
11. Fluorescence-the emission of light by a substance that has absorbed light or other EMR of a different wave length
12. Refraction-When a wave changes direction
13. Propagation-Any of the ways in which waves travel
13.1. New node
14. Frequency-the number of occurrences per unit time
15. Energy-is the transport of energy by a wave
16. Wavelength-the spatial period of the wave
17. Speed-the velocity in which the wave moves
18. Reflection-Angle of a wave on a surface
19. Phosphorescence-Material that does not immediately re-emit the radiation it absorbs.
20. Transparent-the physical property of allowing light to pass through a material.
