Abstract
Welcome to the AtomicEmission system!
24-Sep-97
The AtomicEmissions system is a set of applets which can be used to
demostrate electron state changes in an atom and photonic emission.
On these pages you will find links to various instances of the
AtomicEmissions system of applets.
Interactive control
With interactive control the user can place an electron in a state
and observe the state changes and the photons emitted. The user
imparts energy onto an electron by selecting a higher state for the
electron the begin at. Then the user selects a lower state, which
begins a cascading series of automatic state changes, with a photon
being emitted at each energy level, until the ground state is
reached. At this point the user may repeat the exercise.
The display of waves will be removed:
-
When the electron is moved to a higher state, and
-
When the user clicks on the area where the waves are displayed.
See the HTML sourcecode for an explanation of the tags for
modifying the behavior of the applet, and for more details on the
implementation of the applet, see the
README
file.

Automatic generation
An automatic generation system is a set of three applets which can
be used to generate a spectral analysis graph of a given atom. The
user selects a wavelength for a monochromatic lightsource, which emits
photons which the atom absorbs; for each photon absorbed, the electron
then automatically begins a series of state changes, emitting photons,
until the ground state is reached. Each photon emitted is registered
by a graph, which counts the number of occurances of each wavelength.
This generates a spectrum.
To reset the graph, click on the graph and all entries will be
removed.
