Electromagnetic Radiation by Mind Map: Electromagnetic Radiation

1. Interference-Occurs when a new wave patter is created by the collision of two or more waves

2. Absorption-The way in which energy is taken up by other matter

3. Scattering-When a waves collides with something to change its path

3.1. New node

3.1.1. New node

4. Polarization-Orientation of the waves electrical field at its oscillation

5. Opaque-the degree to which light is blocked

6. Translucent-Allows light to pass through diffusely.

7. Fluorescence-the emission of light by a substance that has absorbed light or other EMR of a different wave length

8. Refraction-When a wave changes direction

9. Diffraction-When a waves collides with something

10. Propagation-Any of the ways in which waves travel

10.1. New node

11. Frequency-the number of occurrences per unit time

12. Energy-is the transport of energy by a wave

13. Wavelength-the spatial period of the wave

14. Speed-the velocity in which the wave moves

15. EMR Spectrum-The range of all possible frequencies in Electromagnetic radiation

15.1. Band/Frequecies and Examples

15.1.1. 10^3-Radio

15.1.2. 10^-2-Microwave

15.1.3. 10^-5-infrared

15.1.4. .5x10^-5-Visible

15.1.5. 10^-8-Ultraviolet

15.1.6. 10^-10-Xray

15.1.7. 10^-12 Gamma Ray

16. Representations

16.1. Wave-Example-Ocean Wave

16.2. Ray-idealized narrow beam of light

16.3. Particle-matter that makes up the wave

16.4. Wave front-Line of points having the same phase

16.5. Wave packet-A short "burst" of wave that travels as a unit

17. Dispersion-Wave is not uniform, becomes frequency dependent

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.
