It is used to see the colours that it gives off, if you know the colours you then know what atom it is.
The Spectra.
The emission spectrum can be used to determine the composition of a material
diversity so important to the study of human relations
Scientists study stellar spectra to learn about their properties such as temperature, chemical composition and relative chemical abundances, radial velocity, rotational speed etc.
Science is the study of how life works but not why it is here so it is the important study of almost anything.
So far, no. Spectra has never kissed anyone.
i've treid i mean Abbyey is in study howl and spectra in creatures' lounge but i don't think you can talk to them
What is science?
It is important to study economics so that you understand the market. You need to understand why you pay what you do for the things you value.
spectra (shows the composition)
It is used to measure and study properties of light. It is used in physical and analytical chemistry to study the unique spectra of atoms and molecules.
That seems like a question you should be answering for us. I can think of several reasons for doing so, but why you specifically are doing it, you should know better than we do.
