Photon is the name given to a quantum of light or other electromagnetic radiation.
Taking the electron transitions associated with visible and ultraviolet interactions with matter as an example, absorption of a photon will occur only when the quantum energy of the photon precisely ...
The photon along with the W and Z provide the necessary pieces to unify the weak and electromagnetic interactions.
Suggested by De Broglie in about 1913, the path to the wavelength expression for a particle is by analogy to the momentum of a photon.
Explanation of the absorption of photons in an hydrogen atom and its energy levels. Use of the Bohr and Rydberg equations.
The APS is a national synchrotron radiation research facility located at Argonne National Laboratory near Chicago, Illinois, USA
Information about E=hf and discussion about the energy required by photons to promote electrons to higher levels.
A web site explaining the basics of SPECT. There are no images to view but the site links back to a medical imaging homepage which explains other techniques.
A short page dealing with the atomic explanation of lasers. Although brief and lacking detail there is a good little applet which shows what happens when an excited atom is struck by a photon.
