|
Angstrom
Nanometer |
1 x 10 raised -10 meters
1 x 10 raised to negative 9 meters difference is power of 10 ` |
|
|
Wavelength
|
distance from crest to crest
|
|
|
Frequency
|
number of waves/ time
|
|
|
The Electromagnetic Spectrum
As wavelength gets longer |
frequency gets shorter
|
|
|
As wavelength gets shorter
|
frequency gets higher
|
|
|
xf = c
|
x = wavelength
f = frequency c = speed of light 3 x 10 raised to 8 m/sec |
|
|
Radiation can be treated as
E = hc/x hc = planks constant |
particles and waves
|
|
|
Dual Split Experiment...Thomas Young
|
Proved the weird duality of particles and waves
|
|
|
Heisenberg's Uncertanity Principle
|
The more precisely the position of an electron is known, the less precisely the momentum is known
|
|
|
Bohr's model more accurately presents a PROBABILITY as to the
|
location of an electron.
|
|
|
Missing weight or mass defect
|
if we add up the components of an Carbon 12 unit and compare it to the actual weight of a C-12 there is a difference.
|
|
|
Mass Defect
|
The difference between the weight of an atom and the sum of its components
|
|
|
Binding energy
|
the amount of energy it takes to break apart an atom from its components
|
|
|
As the number of particles in a nucleus increases, the binding energy also
|
increases to a point where it starts to decrease.
|
|
|
fission = this is what we use in Nuclear Medicine
|
