Nyob rau hauv physics thiab chemistry, wave-particle duality tuav lub teeb thiab teeb meem pom cov khoom ntawm ob nthwv dej thiab ntawm cov khoom. Lub ntsiab lus tseem ceeb ntawm quantum mechanics, duality hais txog qhov tsis txaus ntawm cov ntsiab lus zoo li "particle" thiab "yoj" los piav qhia txog tus cwj pwm ntawm quantum khoom.
Yuav ua li cas yog nthwv dej thiab particle?
Tseeb tuaj yeem piav tau ob qho tib si raws li nthwv dej thiab ua ib feem. Muaj ob qhov kev sim tshwj xeeb uas tau nthuav tawm ob qhov xwm txheej ntawm lub teeb. Thaum peb xav txog lub teeb ua los ntawm cov khoom, cov khoom no hu ua "photons". Photons tsis muaj huab hwm coj, thiab txhua tus muaj lub zog tshwj xeeb.
Yuav ua li cas yog nthwv dej thiab hais lus?
(Phys.org) - Lub teeb coj ob qho tib si raws li ib qho thiab ua nthwv dej. Txij li hnub Einstein, cov kws tshawb fawb tau sim ua ncaj qha saib ob qho tib si ntawm lub teeb tib lub sijhawm.
Puas electrons puas muaj cov khoom ntawm ob lub nthwv dej thiab cov khoom?
Lub teeb nthuav tawm nthwv dej-particle dual, vim nws nthuav tawm cov khoom ntawm ob lub nthwv dej thiab hais. … Electrons, piv txwv li, pom zoo ib yam ntawm kev cuam tshuam tus qauv zoo li lub teeb ua thaum lawv tshwm sim ntawm ob txoj hlua.
Puas tag nrho cov nthwv dej puas muaj cov khoom particle?
Raws li Albert Einstein sau: … Los ntawm kev ua haujlwm ntawm Max Planck, Albert Einstein, Louis de Broglie, Arthur Compton, Niels Bohr, Erwin Schrödinger thiab ntau lwm tus, txoj kev tshawb fawb tam sim no tuav tau tias tag nrho cov khoom pov thawj yoj xwm thiab vice versa.

Ntawm qhov dej siab tshaj plaws puas tau nthwv dej?
António Laureano thov kom tau caij nthwv dej loj tshaj plaws ntawm Praia do Norte hauv Nazaré, Portugal. Thawj qhov ntsuas qhia tias 101.4-ko taw (30.9 meters) nthwv dej. Lub Kaum Hli 29, 2020, tus neeg caij nkoj hauv Portuguese sawv ntxov sawv ntxov thiab tsis ntseeg nws qhov muag .
Puas yog qhov kev ncua deb ntawm cov kab txuas txuas ntxiv ntawm nthwv dej?
Qhov kev ncua deb ntawm cov crests successive crests (los yog successive troughs) yog txhais raws li the wavelength. Lub sij hawm dhau mus ntawm kev hla ntawm ob qho kev ua tiav los ntawm qhov chaw muab yog lub sijhawm ntawm nthwv dej . Yuav ua li cas yog lub crest nyob rau hauv nthwv dej?
Puas muaj cov yam ntxwv ntawm ob qho tib si transverse thiab longitudinal nthwv dej?
Transverse nthwv dej yog ib txwm muaj cov lus tsa suab ua rau perpendicular rau yoj yojIb nthwv dej ntev yog nthwv dej uas cov khoom nruab nrab ntawm qhov nruab nrab txav mus rau qhov sib npaug mus rau qhov kev taw qhia nthwv dej. … Cov nthwv dej ntev yog ib txwm ua los ntawm cov lus tsa suab ua rau tib lub sijhawm mus rau nthwv dej .
Puas yog lub suab nthwv dej piv txwv ntawm lub nthwv dej compressional?
Suab nthwv dej taug kev los ntawm huab cua yog qhov tseeb ntev nthwv dej nrog compressions thiab tsis tshua muaj. Raws li lub suab dhau los ntawm huab cua (lossis ib qho nruab nrab ntawm cov kua dej), cov khoom ntawm huab cua tsis vibrate nyob rau hauv ib tug transverse .
Cov txheej txheem twg ntawm cov kwj dej kais dej nqus cov khoom noj?
Mucosa. Lub mucosa, tsim los ntawm cov kab mob yooj yim epithelium, yog txheej sab hauv ntawm txoj hnyuv (GI) ib puag ncig. Nws yog qhov nqus thiab secretory txheej ntawm GI ib puag ncig . txheej dab tsi absorbs as-ham? Lub luag haujlwm tseem ceeb ntawm txoj hnyuv meyog qhov nqus ntawm cov as-ham thiab cov zaub mov muaj nyob hauv cov zaub mov.
