A mechanical yoj yog a yoj uas yog oscillation ntawm qhov teeb meem , thiab yog li ntawd hloov lub zog los ntawm qhov nruab nrab. Thaum nthwv dej tuaj yeem txav mus ntev, kev txav mus los ntawm qhov nruab nrab ntawm kis-cov khoom siv-yog txwv. Yog li ntawd, cov khoom siv oscillating tsis txav deb ntawm nws txoj haujlwm pib sib npaug.

Ib yam li ntawd, nws raug nug, qhov kev sib raug zoo ntawm nthwv dej thiab teeb meem yog dab tsi?

Cov yoj kev ua haujlwm rau cov khoom siv feem ntau hu ua a teeb meem yoj . Cov kev sib raug zoo ntawm momentum thiab wavelength rau teeb meem nthwv dej yog muab los ntawm p = h/λ, thiab cov kev sib raug zoo lub zog thiab zaus yog E = hf.

Tom qab ntawd, lo lus nug yog, lub tshuab hluav taws xob thiab hluav taws xob tsis zoo sib xws thiab txawv li cas? Muaj ob hom nthwv dej : mechanical waves zoo li lub suab uas yuav tsum taug kev los ntawm qhov nruab nrab zoo li huab cua, thiab electromagnetic tsis zoo li lub teeb uas tsis. Ob hom ntawm nthwv dej hloov lub zog hauv a yoj -zoo li yam, raws li qhov ntawd yog dab tsi a yoj yog, ib qho kev cuam tshuam lub cev ntawm lub zog raug xa mus rau qhov chaw thiab lub sijhawm.

Ib yam li ntawd, cov tshuab hluav taws xob puas tuaj yeem taug kev los ntawm cov teeb meem?

Mechanical waves taug kev los ntawm qhov teeb meem , ua rau nws vibrate, nthuav thiab cog lus, txav nce thiab nqis, sab rau sab, lossis hauv voj voog. Lawv suav nrog dej nthwv dej , suab nthwv dej , thiab seismic nthwv dej . Lub teeb yog hloov ntawm lub zog ntawm electromagnetic nthwv dej.

Mechanical waves thiab electromagnetic vuag muaj dab tsi?

Electromagnetic tsis txawv ntawm mechanical waves hauv lawv ua tsis xav tau ib qho nruab nrab los nthuav tawm. Qhov no txhais tau tias electromagnetic tsis tuaj yeem taug kev tsis tsuas yog los ntawm huab cua thiab cov khoom siv, tab sis kuj los ntawm lub tshuab nqus tsev.
