|
Electromagnetic Spectrum |
-made up of different types of waves |
|
|
Waves |
-transfer of energy -no matter -electric + magnetic components |
|
|
Properties of Waves Wavelength |
-the length of one wave (meters)
-from crest to crest |
|
|
Properties of Waves Energy |
-Radiant Energy (Joules) |
|
|
Properties of Waves Frequency |
-the number of waves that pass by in one second (Hertz) |
|
|
Properties of Waves Speed |
-how fast the wave is traveling (meters/second) -3.00 X 108 meters/second -all waves have the same speed |
|
|
Types of Relationships |
-Direct: both variables behave the same way -Indirect: the variables behave in opposite ways |
|
|
Photons |
-"bundle" on visible light -has energy -interact with electrons in matter -one second = one billion photons |
|
|
Types of Electrons |
-Valance Electrons: outer most level of electrons -Core Electrons: inner most level of electrons |
|
|
States of Electrons Ground State |
-electrons are normal -they are on the level where they belong |
|
|
States of Electrons Excited State |
-an electron has absorbed energy from a photon -"jumps" to an outer level (farther from the nucleus) -burn off all the extra energy and "fall" back down -release a certain wave that gives off color |
