Kev tshawb fawb pib ntawm x-ray, X-Ray yog dab tsi? — https://hv-caps.biz
X-rays yeej yog tib yam li pom lub teeb pom kev zoo. Ob leeg yog cov ntaub ntawv wavelike ntawm electromagnetic zog nqa los ntawm cov khoom hu ua photons Light. Qhov txawv ntawm X-rays thiab pom lub teeb rays yog lub zog theem ntawm tus kheej photons. Qhov no kuj qhia raws li lub wavelength ntawm lub rays.
Peb ob lub qhov muag yog rhiab heev rau qhov tshwj xeeb wavelength ntawm pom lub teeb, tab sis tsis mus rau lub luv luv wavelength ntawm siab zog X-ray tsis los yog ntev wavelength ntawm lub qis zog xov tooj cua tsis.
Pom pom lub teeb photons thiab X-ray photons yog ob qho tib si tsim los ntawm kev txav ntawm electrons hauv atoms. Cov hluav taws xob nyob sib txawv zog, los yog orbitals, nyob ib ncig ntawm lub atom lub nucleus. Thaum ib qho hluav taws xob poob mus rau qis orbital, nws yuav tsum tso qee lub zog - nws tso tawm lub zog ntxiv rau hauv daim ntawv ntawm photon. Lub zog theem ntawm photon nyob ntawm seb qhov hluav taws xob poob qis ntawm orbitals. (Saib nplooj ntawv no kom paub meej txog cov txheej txheem no.)
Thaum lub photon sib tsoo nrog lwm lub atom, lub atom yuav nqus tau lub photon lub zog los ntawm kev txhawb nqa ib qho hluav taws xob mus rau qib siab dua. Yuav kom qhov no tshwm sim, lub zog theem ntawm photon yuav tsum ua kom haum lub zog sib txawv ntawm ob txoj haujlwm electron. Yog tias tsis yog, photon tsis tuaj yeem hloov electrons ntawm orbitals.
Cov atoms uas ua rau koj cov ntaub so ntswg nqus pom lub teeb photons zoo heev. Lub zog theem ntawm photon haum nrog ntau lub zog sib txawv ntawm cov haujlwm electron. Cov xov tooj cua tsis muaj zog txaus los txav cov electrons ntawm orbitals hauv cov atoms loj dua, yog li lawv dhau los ntawm ntau yam khoom. X-ray photons kuj dhau los ntawm ntau yam, tab sis rau qhov tsis sib xws: Lawv muaj zog ntau dhau.
Lawv tuaj yeem, txawm li cas los xij, khob lub electron deb ntawm ib qho atom tag nrho. Qee lub zog los ntawm X-ray photon ua haujlwm cais cov electron ntawm lub atom, thiab tus so xa cov hluav taws xob ya mus los ntawm qhov chaw. Lub atom loj dua yuav nqus tau X-ray photon nyob rau hauv txoj kev no, vim hais tias cov atoms loj dua muaj zog sib txawv ntawm orbitals - lub zog ntau dua sib npaug zog ntawm photon. Cov atoms me me, qhov twg cov electron orbitals sib cais los ntawm kev dhia qis hauv lub zog, tsis tshua muaj peev xwm nqus X-ray photons.
Cov nqaij mos hauv koj lub cev yog tsim los ntawm cov atoms me, thiab yog li tsis nqus X-ray photons tshwj xeeb tshaj yog zoo. Cov calcium atoms uas ua rau koj cov pob txha loj dua, yog li lawv zoo dua ntawm kev nqus X-ray photons.
