Spectroscopy:
The study of waves, emission, and absorption.
Speed of Light:
c = 2.998e8 m/s
Speed of Sound:
343.06 m/s
The electromagnetic field:
Particles are being moved very fast, either radio, x-rays, light waves, etc.
AKA carries energy.
c = Speed of Light
Lambda = Wavelength
v = Frequency
Wavelength (lambda):
The peak to peak distance in nanometers
The lower the wavelength the more energy, AKA gamma-rays rock (HULK)
Amplitude:
Height over the center line
Intensity (brightness):
amplitude^2
Frequency:
How many cycles in a second, like how long it is
In Hz
- The higher Hz, the shorter wavelength
- The lower Hz, the longer wavelength
ALSO:
The higher the frequency the higher the Energy.
When an electric current passes through a gas, the gas emits light, as exited electrons are separated with the atom, and then they recombine and emit a photon.
Spectral Lines:
Specific lights that are emitted or absorbed by an atom/molecule.
Visible Region of light from a Hydrogen Atom:
R (Rydberg’s Constant): 3.29e15 Hz
Balmer Series:
Consists of the visible light region
N1 = 2
Lyman Series:
Consists of UV light region
N1 = 1
