Hi,
This must be a textbook question but I couldn't find exact definitions(quantitative) of these measurements
Extinction spectra:
Absorption spectra:
Transmission spectra:
eg.
Lets say electric field spectrum of some location/surface is calculated by illuminating a source with and without the presence of an object.
With the presence of the object = [itex]E_{transmitted}(\omega)[/itex]
Without the presence of the object = [itex]E_{incident}(\omega)[/itex]
Absorption spectra = [tex]\frac{E_{incident}(\omega) - E_{transmitted}(\omega)}{E_{incident}(\omega)}[/tex]
Should it be [itex] E [/itex] or [itex] E^2 [/itex] (energy) ?
Can somebody point me to a book/ web resource or the answers to these definitions?
Thanks in advance
