Qhov sib txawv tseem ceeb ntawm photon thiab quantum yog tias photon yog ib qho me me, qhov quantum yog qhov ntsuas ntau.
Photon yog ib qho me me thaum quantum yog ib pob ntawv sib cais nrog lub zog khaws cia hauv nws. Photon thiab quantum yog ob lub ntsiab lus tseem ceeb hauv physics niaj hnub no. Tsis tas li ntawd, cov ntsiab lus no muaj txiaj ntsig zoo hauv thaj chaw xws li quantum physics, quantum chemistry, electromagnetic theory, optics, particle physics, thiab lwm yam. Cov ntsiab lus no tseem ceeb heev hauv ntau daim ntawv thov hauv ntiaj teb xws li LASERs, high-resolution microscopy, ntsuas molecular. nrug, quantum cryptography, thiab photochemistry.
Photon yog dab tsi?
Photon yog ib qho me me uas tsis muaj qhov sib txuas. Elementary hais yog lub tsev blocks ntawm lub ntug; tag nrho lwm cov khoom yog tsim los ntawm cov khoom no. Photons yog nyob rau hauv qeb ntawm bosons theem pib. Albert Einstein yog leej txiv ntawm lub tswv yim niaj hnub ntawm photons. Nws siv lub tswv yim no los piav qhia cov kev soj ntsuam uas tsis haum nrog cov qauv nthwv dej ntawm lub teeb.
Ib photon yog ib qho particle nrog xoom so, tab sis nws muaj qhov sib npaug. Tsis tas li ntawd, nws tsis muaj hluav taws xob. Tsis tas li ntawd, nws tsis lwj spontaneously nyob rau hauv qhov chaw. Ntxiv mus, nws txav ntawm qhov ceev ntawm lub teeb hauv qhov chaw. Peb tuaj yeem pom lub zog ntawm photon los ntawm E=hf, qhov twg E yog lub zog, f yog qhov zaus ntawm photon thiab h yog Plank qhov tas li. Peb kuj tuaj yeem muab qhov sib npaug no rau hauv daim ntawv E=hc / λ, qhov ceev ntawm lub teeb yog c thiab λ yog wavelength.
Daim duab 01: Thaum Electron txav los ntawm Qib Siab Zog mus rau qib qis zog, Photon raug tso tawm (nws muaj zog hv)
Tsis tas li ntawd, photons, zoo li tag nrho lwm yam khoom quantum, nthuav tawm yoj-zoo li thiab cov khoom zoo li particle. Thiab, qhov no dual nthwv dej-particle xwm yog lub tswvyim peb hu ua nthwv dej-particle dual ntawm photon. Photons raug tso tawm hauv ntau cov txheej txheem ntuj; Piv txwv li, thaum ua kom muaj nqi, thaum lub sij hawm molecular, atomic, los yog nuclear hloov mus rau qis dua, thiab thaum ib tug particle thiab nws cov khoom antiparticle nyob rau hauv kev puas tsuaj.
Quantum yog dab tsi?
Lo lus quantum los ntawm Latin 'quantus' lub ntsiab lus 'ntau npaum li cas'. Lub quantum yog 'ib pob ntawv sib cais' nrog lub zog khaws cia hauv nws. Lub zog ntawm qhov teeb meem tsis tas mus li. Qhov ntawd txhais tau hais tias kev hloov pauv ntawm txhua lub zog tsis tuaj yeem ua tau. Cov kws tshawb fawb tau tshawb pom tias lub zog yog quantized thiab nws hloov mus rau hauv discrete units (los yog pob ntawv) ntawm loj hf. Peb hu txhua lub pob khoom ntawm lub zog ua 'quantum'.
Daim duab 02: Ib pob ntawv Wave sawv cev rau Quantum Particle
Piv txwv li, photon yog ib qho quantum ntawm lub teeb. Lub plural ntawm quantum yog quanta. Max Plank nrhiav tau lub tswvyim ntawm quantization. Nws siv lub tswv yim no los piav qhia txog qhov emission ntawm hluav taws xob los ntawm cov khoom cua sov; peb hu lub cev dub tawg no.
Qhov txawv ntawm Photon thiab Quantum yog dab tsi?
Photon yog qhov tsawg tshaj plaws uas tsis sib xws lossis quantum ntawm hluav taws xob hluav taws xob thaum quantum yog qhov sib txawv ntawm lub zog sib npaug hauv qhov loj rau qhov zaus ntawm cov hluav taws xob nws sawv cev. Yog li ntawd, qhov sib txawv tseem ceeb ntawm photon thiab quantum yog tias photon yog ib qho tseem ceeb, qhov quantum yog qhov ntsuas ntawm qhov ntau.
Ntxiv mus, lwm qhov sib txawv tseem ceeb ntawm photon thiab quantum yog qhov photon tseem ceeb raws li quantum ntawm electromagnetic tawg thaum quantum tseem ceeb los ntsuas kom muaj nuj nqis ntawm subatomic scale.
Summary – Photon vs Quantum
Peb tuaj yeem piav qhia txog quantum raws li qhov ntsuas ntawm qhov ntau, tab sis photon tsis yog hais txog qhov ntsuas qhov ntau. Qhov tseeb, peb tuaj yeem piav qhia txog photon ua lub zog quantum. Li no, qhov sib txawv tseem ceeb ntawm photon thiab quantum yog tias photon yog ib qho tseem ceeb, whereas quantum yog ib qho kev ntsuas ntawm ntau.
