Muaj peb qhov ntsuas tau ntawm yoj motion: amplitude , wavelength, thiab zaus. Ib qho kev sim kom meej yog Young qhov kev sim ob npaug, uas pom tau tias lub teeb ci ntawm ob lub qhov nyob rau hauv ib qho screen qhia ib qho kev cuam tshuam tus yam ntxwv ntawm nthwv dej ntawm lub teeb, es tsis yog hais.

Tib neeg kuj nug tias, lub teeb muaj dab tsi?

Qhov tseem ceeb khoom ntawm pom teeb yog kev siv zog, kev nthuav tawm kev taw qhia, zaus lossis wavelength spectrum, thiab polarization, thaum nws ceev hauv lub tshuab nqus tsev, 299, 792, 458 meters ib ob, yog ib qho tseem ceeb ntawm qhov xwm txheej.

Kuj Paub, lub teeb yoj yog dab tsi? Lub teeb nthwv dej yog cov ntaub ntawv txav zog ua los ntawm cov khoom me me hu ua photons. Cov kws tshawb fawb feem ntau hais txog lub teeb nthwv dej raws li electromagnetic nthwv dej vim hais tias lawv ua li lub npe hu ua electromagnetic spectrum. Lub sij hawm electromagnetic txhais tau tias nthwv dej yog ob qho tib si hluav taws xob thiab sib nqus.

Hais txog qhov no, 3 yam khoom ntawm lub teeb yog dab tsi?

Peb thawj cov khoom ntawm lub teeb yog ceev, kev xav, thiab xim. Qhov ceev ntawm teeb yog 300, 000 Kilometers ib ob, uas yog lub siab ceev txwv ntawm txhua yam hauv lub ntiaj teb. Cov teeb hais, los yog photons, xav txog lwm yam hais los yog pawg thiab txuas ntxiv mus rau tib lub ceev.

Dab tsi yog cov yam ntxwv ntawm lub suab nthwv dej?

Suab yog ib tug longitudinal yoj uas muaj compressions thiab rarefactions taug kev los ntawm ib tug nruab nrab. Lub suab nthwv dej tuaj yeem piav qhia los ntawm tsib yam ntxwv: Wavelength, Amplitude , Lub Sijhawm-Lub Sijhawm, Ntau zaus thiab nrawm lossis nrawm. Qhov tsawg kawg nkaus nyob deb uas lub suab nthwv dej rov ua nws tus kheej yog hu ua nws lub wavelength.
