Electromagnetic Radiation

1. Spectrum (band) Example

1.1. Largest= Radio

1.2. Microwave

1.3. Infrared

1.4. Visble

1.5. Ultraviolet

1.6. Xray

1.7. Smallest =Gamma Ray

2. Diffraction occurs when a wave runs into something; the wave begins to bend and move around the object

3. Polarization= the orientation of a waves electric field at a point in its ossillation

4. Phosphorescence= a substance that does not readmit radiation from which it has previously observed

5. Electromagnetic Waves

5.1. Wavelength is equal to the speed of light divided by its frequency

5.2. Propagation is the way in waves travel

5.3. Frequency= the number of waves per unit time

6. Dispersion= occurs when a waves velocity is not uniform; it is dependent on frequency

7. Fluorescence-emission of light from an electromagnetic wave

8. Reflection= the angle at which a wave is on a surface is the same angle at which is being reflected

9. Interference occurs when two or more waves come together and create a new wave pattern

10. Absorption= the way in which energy is taken up by other matter

11. Scattering occurs when something in a particular medium makes a deviate from a straight trajectory or path
