What is power?
|
POWER= engery per time or a watt= joules per secondPOWER COMPANIES USE kilowatts per hour
|
|
What are the three wave properties and how are they related?
|
SPEED= velocity= c= 3 times 108 meters per secondFREQUENCY= # of pearks that pass a loacation in a given time Units= HZ= 1/sWAVELENGTH= Distance between two peaks UNITS= KM,M, CM etcEQUATION= F= V/ WAVELENGTH
|
|
What is a photon?
|
Smallest bundle of light energy or a particle of light
|
|
Composition EARTH AIR SUN'S AIR?, MOST COMMON OF EARTHS FEATURE Density OF SUN= DENSITY OF EARTH Blackbody temp of sun and earth?How old is the earth approximately? |
Composition EARTH AIR= NITROGEN AND OXYGENSUN’S AIR= HYDROGEN AND HELIUM MOST COMMON OF EARTHS FEATURES= IRON OXYGEN, SILICON AND MAGNESIUM,Earth is approximately 4.5 billion years old
Density OF SUN=1.4G/CM^-3 DENSITY OF EARTH= 5.5G/CM^-3, DENSITY OF EARTH IS THEREFORE 4 TIMES MORE3.3 TIMES MORE MASSIVE |
|
Energy of Photons (How does it relate to
frequency and wavelength?)
|
A PHOTONS ENGERGY IS
PROPORTIONAL TO FREQUENCY, A PHOTONS WAVELENGTH IS INVERSELY PROPORTIONAL TO
ENERGY

|
Eddington’s Final Theory?
|
Gravitational forces pressurize the center of the Sun.
2) Compression heats the interior (he thought to 40 million K). 3) Thermal collisions strip electrons from their nucleus, creating a
plasma. 4) Free protons collide and stick to form helium nuclei.
5) The mass difference between H and He is converted to energy and released as light!
|
|
The relationship between geology and the demise of Kelvin-Helmholz contraction
as a theory for solar energy generation.
|
Atomic scientists had discovered that certain heavy elements would decay into lighter ones by emitting a radioactive particle.
|
|
Example of fission
|
Hahn was trying to make heavier elements by hitting Uranium with neutrons. Instead he kept getting results consisting of lighter elementsInstead she concluded that Uranium had `fissioned` into lighter elements, with the difference in mass going into energy!

|
What is terra, giga, mega, kilo, micro, nano?
|
TERA=1012giga= 10>9mega?6KILO=10>3MICRO=10>-6NANO=10>-9
|
|
What are Alpha, Beta and Gama particles?
|
Alpha= Helium Nuclei Beta= electron (break neutron up)Gamma=Photon (high energy)
|
|
What is a chain reaction? What does enriching Uranium accomplish?
Radiation (alpha, beta, and gamma, How far can they penetrate matter?)
|
???
|
|
Molecular energy states. The difference (energy and mechanism) between
electrical, vibrational and rotational states and what it has to do with the way light
interacts. Types of Spectra (absorption, emission, and blackbody) What radiative transfer is (generally) The ways that solar radiation interacts with our atmosphere (photo-dissociation
and the stratosphere, ionization in the thermosphere, etc.). What the causes the Ozone hole and greenhouse effect.
|
???
|
|
1 What the binding energy is. |
Amount of energy necessary for an electron to escape the atom
|
|
What an ion is and what plasma is.What is ionization?
|
Ionization is when an atom asorbs light greater than the binding energy the electron escapes The atom is thereofre left with a positive charge and is called an ion The ions and these free electrons= plasmas (if done with molecules its called a molecular ion)
