What is line emission spectrum? |
|
Answer» Kost welcome dear ?✌ Thanks for your answers... ya it\'s helpful?✌ The\xa0emission spectrum\xa0of a\xa0chemical element\xa0or\xa0chemical compound\xa0is the spectrum of\xa0frequencies\xa0of\xa0electromagnetic radiation\xa0emitted due to an\xa0atom\xa0or molecule making a\xa0transition\xa0from a high energy state to a lower energy state. The\xa0photon energy\xa0of the emitted\xa0photon\xa0is equal to the energy difference between the two states. There are many possible electron transitions for each atom, and each transition has a specific energy difference. This collection of different transitions, leading to different radiated\xa0wavelengths, make up an emission spectrum. Each element\'s emission spectrum is unique. Therefore,\xa0spectroscopy\xa0can be used to identify elements in matter of unknown composition. Similarly, the emission spectra of molecules can be used in chemical analysis of substances. Hope it will help you ?✌ Hi Sodium emits yellow light while potassium gives out violet light. If this light is resolved in a spectroscope, some isolated coloured\xa0lines\xa0are obtained on the photographic plates separated from each other by dark spaces. This\xa0spectrum\xa0is called\xa0line emission spectrum\xa0on\xa0line spectrum. |
