Provide one example of the interaction between matter and lightthat you observe around you. Tell us the following about thatinteraction:
1). What are the bonds or atoms that are excited in thisinteraction? You might have to guess on this one, but that is allright. Try to at least guess what type of molecules your materialconsists of.
2). What does the interaction between the photons and materialsresult in? (There are three de-excitation mechanisms once the atomsin the materials are excited.)
3). Is it possible to obtain longer wavelength photons from theinteraction of photons with molecules?Ă‚Â Ă‚Â Is that aviolation of the conservation of energy?
4). What type of photon did the material interactwith?Ă‚Â Ă‚Â What energy range is that photon in?
