Vim li cas cov khoom muaj qhov ruaj khov thiab ntim?
1 Teb. Cov khoom muaj qhov ruaj khov thiab nyob hauv ib lub ntim ruaj khov. Vim hais tias cov khoom nyob rau hauv cov kua yog sib ze heev (Ntsuas ntxiv sib nrug tshaj nyob rau hauv cov khib nyiab) cov kua tsis yooj yim compress, yog li lawv ntim yog tsau. Gases kuj tuaj yeem ntws, yog li tuav cov duab ntawm lawv lub thawv tag nrho
Cov cuab yeej twg ua rau qhov sib txawv ntawm kev nce qib thiab nyob ruaj khov nthwv dej?
Txawm li cas los xij, ntawm lub nthwv dej nyob ruaj ruaj, txawm li cas los xij, thaum ob lub nthwv dej sib xyaw ua ke / superimpose rau ib leeg, lawv tsim cov nodes thiab anti-nodes raws li lub wavelength / zaus ntawm nthwv dej. Hais txog theem, ib nthwv dej loj tuaj yeem xav tias yog ib nthwv dej nkaus xwb, yog li tsis muaj theem sib txawv vim nws tsis koom nrog ob lossis ntau dua nthwv dej
Dab tsi tsis muaj qhov ntim ruaj khov lossis zoo li cas?
Cov roj yog ib yam khoom uas tsis muaj qhov ntim thiab tsis muaj qhov tseeb. Khoom thiab kua muaj ntim uas tsis hloov tau yooj yim. Ib qho roj, ntawm qhov tod tes, muaj qhov ntim uas hloov pauv kom haum rau qhov ntim ntawm nws lub thawv. Cov molecules nyob rau hauv ib tug roj yog sib nrug heev piv nrog rau cov molecules nyob rau hauv ib tug khoom los yog kua
Puas yog cov pa roj tsis muaj qhov ruaj khov thiab ntim?
Cov roj yog ib yam khoom uas tsis muaj qhov ntim thiab tsis muaj qhov tseeb. Khoom thiab kua muaj ntim uas tsis hloov tau yooj yim.
