Imibuzo Evame Ukubuzwa

Iyini i-spectra ebonakalayo yezakhi?

I-spectra ebonakalayo ibhekisela kumaphethini ayingqayizivele okukhanya okukhishwayo noma okumuncwa into ngayinye yekhemikhali ngaphakathi kwebanga le-wavelength elibonakalayo (cishe u-380–700 nm). Lapho ama-athomu ejabule, ama-electron awo ashintshana phakathi kwamazinga wamandla, akhiphe ama-photon kumaza amaza athile. Lokhu kukhiqiza isethi ehlukile yemigqa enemibala—njengomgxivizo weminwe—kuyo yonke into, okuvumela ososayensi ukuthi babone izinto ngobuchule obubizwa nge-spectroscopy.

Kungani ama-elementi ahlukene akhiqiza imigqa ye-spectral ehlukene?

I-elementi ngayinye inesakhiwo se-athomu esihlukile esinokucushwa kwama-electron namaleveli wamandla. Lapho ama-electron egxuma phakathi kwala mazinga, akhipha noma amunce ukukhanya kumaza wamaza anembile anqunywa igebe lamandla. Ngenxa yokuthi awekho ama-elementi amabili abelana ngamalungiselelo ezinga lamandla afanayo, yonke into ikhiqiza iphethini ye-spectral eyodwa. Lesi simiso sibalulekile emikhakheni efana nesayensi yezinkanyezi, ikhemistri, nesayensi yezinto.

Isetshenziswa kanjani i-emission spectroscopy ezinhlelweni zomhlaba wangempela?

I-spectroscopy ekhishwayo isetshenziswa kakhulu ukuze kutholwe ukwakheka kwamakhemikhali ezinkanyezi, ukuhlonza izinto ezingaziwa kumalebhu e-forensic, ukuqapha izinqubo zezimboni, nokuhlola amasampula emvelo ukuze uthole ukungcola. Iphinde idlale indima ebalulekile ekulawuleni izinga lezinsimbi nama-alloys. Abacwaningi nabafundi abahlola izihloko ezifana nalezi bangafinyelela izinsiza zokufunda ezihlelekile ngokusebenzisa izinkundla ezifana ne-Mewayz, ehlinzeka ngamamojula angu-207 aqala ku-$19/mo.

Uyini umehluko phakathi kokukhishwa kwe-spectra nokumuncwa?

I-spectrum ekhishwayo ibonisa imigqa enemibala egqamile kungemuva elimnyama, ekhiqizwa lapho ama-athomu ajabulile ekhipha amandla njengokukhanya. I-spectrum yokumuncwa ibonisa imigqa emnyama ngokumelene nengemuva lombala oqhubekayo, okwenzeka lapho ama-athomu emunca ubude obuthile obuvela ekukhanyeni okumhlophe okudlula kuwo. Zombili lezi zinhlobo zembula isici sobude obufanayo besici esithile futhi zingamathuluzi abalulekile kukhemistri yokuhlaziya kanye ne-astrophysics.
