Qhov sib txawv tseem ceeb ntawm Compton tawg thiab Thomson Scattering yog tias Compton tawg yog ib hom inelastic scattering, whereas Thomson tawg yog ib hom elastic tawg.
Hauv luv luv, Compton tawg tuaj yeem txhais tau tias yog kev tawg ntawm photon thaum muaj kev cuam tshuam nrog cov khoom siv hluav taws xob xws li hluav taws xob. Meanwhile, Thomson tawg yog ib hom elastic tawg ntawm electromagnetic tawg nyob rau hauv lub xub ntiag ntawm ib tug dawb xwb particle.
Compton Scattering yog dab tsi?
Compton scattering yog tawg ntawm photon thaum muaj kev cuam tshuam nrog cov khoom siv hluav taws xob xws li hluav taws xob. Qhov tshwm sim no tau pom los ntawm Arthur Holly Compton. Peb tuaj yeem hu nws cov nyhuv Compton yog tias cov txheej txheem no ua rau txo qis zog ntawm photon. Thaum lub sij hawm Compton scattering, ib feem ntawm lub zog ntawm photon yog pauv mus rau recoiling electron. Nyob rau hauv sib piv, inverse Compton scattering tshwm sim thaum hloov ntawm ib feem ntawm lub zog ntawm ib tug nqi particle mus rau ib tug photon.

Ntxiv mus, Compton tawg yog ib hom inelastic tawg ntawm lub teeb. Qhov no tshwm sim los ntawm ib qho dawb-them particle nyob rau hauv xws li ib txoj kev uas lub teeb tawg yog txawv ntawm qhov teeb meem hluav taws xob. Peb tuaj yeem hu rau qhov kev hloov pauv ntawm lub wavelength ntawm lub teeb Compton hloov.
Tsis tas li ntawd, Compton tawg yog ib qho ntawm plaub txoj kev sib tw uas tuaj yeem tshwm sim thaum photons cuam tshuam nrog teeb meem. Lwm cov txheej txheem peb yog cov nyhuv photoelectric, khub ntau lawm, thiab photodisintegration. Ntawm lawv, Compton tawg yog qhov kev cuam tshuam tseem ceeb tshaj plaws hauv thaj av cuam tshuam lub zog.
Thomson Scattering yog dab tsi?
Thomson tawg yog ib hom elastic tawg ntawm hluav taws xob hluav taws xob nyob rau hauv lub xub ntiag ntawm cov khoom pub dawb. Qhov tshwm sim no tuaj yeem piav qhia los ntawm classical electromagnetism. Thomson tawg tuaj yeem piav qhia raws li qhov txwv tsis pub muaj zog ntawm Compton tawg. Txawm li cas los xij, qhov kev txwv qis dua no muaj nyob rau thaum lub zog photon me dua li qhov loj-zog ntawm particle.

Ntxiv mus, thaum xav txog qhov txwv tsis pub muaj hluav taws xob, hluav taws xob ntawm qhov xwm txheej nthwv dej tuaj yeem ua kom cov khoom siv hluav taws xob nrawm, uas ua rau nws tawm hluav taws xob ntawm tib zaus raws li qhov xwm txheej nthwv dej. Yog li ntawd, lub nthwv dej tau tawg. Thomson tawg yog thawj zaug piav los ntawm J. J. Thomson.
Cosmic microwave keeb kwm yog ib qho piv txwv ntawm Thomson tawg. Nws muaj ib qho me me linearly-polarized tivthaiv uas yog los ntawm Thomson tawg. Ntxiv mus, hnub ci K-corona yog qhov tshwm sim ntawm Thomson tawg ntawm lub hnub ci hluav taws xob los ntawm hnub ci coronal electrons.
Qhov txawv ntawm Compton Scattering thiab Thomson Scattering yog dab tsi?
Compton tawg thiab Thomson tawg yog ob hom txheej txheem tawg. Qhov sib txawv tseem ceeb ntawm Compton scattering thiab Thomson Scattering yog tias Compton tawg yog ib hom inelastic scattering, whereas Thomson tawg yog ib hom elastic tawg.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm Compton tawg thiab Thomson Scattering hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Compton Scattering vs Thomson Scattering
Compton scattering yog tawg ntawm photon raws li kev cuam tshuam nrog cov khoom siv hluav taws xob xws li hluav taws xob. Whereas, Thomson tawg yog ib hom elastic tawg ntawm electromagnetic tawg nyob rau hauv lub xub ntiag ntawm ib tug dawb-them particle. Yog li, qhov sib txawv tseem ceeb ntawm Compton scattering thiab Thomson Scattering yog tias Compton tawg yog ib hom inelastic scattering, whereas Thomson tawg yog ib hom elastic tawg.
