How to Identify Elements
Using a Spectrometer!
A Spectrometer, What is it?
This device is often used in spectroscopy, which is the study of the interaction between matter and electromagnetic radiation. Specifically in spectroscopy, the spectrometer is used to produce spectral lines and then their wavelengths and intensities can be measured.
Identifying Elements
Well, each element has specific characteristics and light patterns. Contained elements are observed in labs for their specific light characteristics. Scientists then compare these samples' patters to the ones they get from the stars. After comparing and contrasting the samples, the scientists are able to identify the elements in the stars.
