erm a simple question. If all light comes from the electrom-photon interference in an atom, that means that we can't obtain a continuous spectrum theoratically. How then is an absorption spectrum possible??
I know this is really late, but there's a good question here that has not been adequately answered.Oerg said:erm a simple question.

A continuous spectrum is possible due to the presence of a wide range of energy levels within a substance. When a substance is heated or excited, its atoms and molecules absorb and emit radiation at different energy levels, resulting in a continuous range of wavelengths in the spectrum.
An absorption spectrum is produced when a substance absorbs certain wavelengths of light, resulting in dark lines on a continuous spectrum. On the other hand, an emission spectrum is produced when a substance emits certain wavelengths of light, resulting in bright lines on a dark background.
The composition of a substance affects its absorption spectrum by determining which wavelengths of light it can absorb. Different substances have different energy levels, which results in different absorption spectra. Additionally, the presence of impurities or other substances can also affect the absorption spectrum.
Absorption spectra can be used in various scientific fields, including astronomy, chemistry, and biology. By studying the absorption spectra of different substances, scientists can determine the composition, temperature, and other properties of celestial bodies, identify unknown substances, and study the behavior of atoms and molecules.
Absorption spectra have numerous applications in our daily lives, including in the fields of medicine, agriculture, and environmental science. For example, doctors use absorption spectra to diagnose medical conditions, farmers use it to determine the nutrient levels in soil, and scientists use it to monitor air pollution levels.
