What is the difference between spectroscopy and spectrophotometry?
1. Spectroscopy is the branch of science concerned with the investigation and measurement spectra produced when matter interacts with or emits electromagnetic radiation.
This included all methods of producing and analyzing light spectra using spectroscopes, spectrographs, spectrometers and spectrophotometers.
2. Spectrophotometry is measuring intensity of light in a part of the spectrum specially as transmitted or emitted by particular substances This is measured using a spectrophotometer
In this use a photometer to measure the intensity of the light which is given out by a substance or intensity of light emitted by it. Measurement involves wave lengths ,energies etc.
