How is a emission spectrum produced
Web17 mei 2024 · How is an emission spectrum produced? Thus, emission spectra are produced by thin gases in which the atoms do not experience many collisions … Web27 nov. 2024 · An emission spectrum is the light emitted when an element in the gaseous state is heated. It is caused when the electrons in excited atoms drop to lower energy states and emit energy as light of specific colours. Each type of element emits its own emission spectrum. How do you identify emission spectra?
