Qhov sib txawv tseem ceeb ntawm cov tshuab tsis muaj zog thiab cov nthwv dej electromagnetic: Tshawb nrhiav seb lawv nthuav tawm hauv peb lub ntiaj teb li cas!

Kev Taw Qhia

Cov nthwv dej yog qhov cuam tshuam uas nthuav tawm hauv nruab nrab. Muaj ntau hom nthwv dej, tab sis nyob rau hauv tsab xov xwm no peb yuav tham txog qhov sib txawv ntawm cov khoom siv hluav taws xob thiab hluav taws xob nthwv dej.

Ondas mecánicas

Mechanical nthwv dej propagated los ntawm cov khoom nruab nrab, xws li huab cua, dej los yog hlua khi. Cov nthwv dej no xav tau qhov nruab nrab los nthuav tawm, vim lawv xav tau qhov nruab nrab elastic kom xa lub zog ntawm ib qho mus rau lwm qhov.

Piv txwv ntawm mechanical waves

• Ondas sonoras
• Wave rau ntawm txoj hlua taut
• Ripples ntawm qhov chaw dej
• Ondas sísmicas

Mechanical nthwv dej tuaj yeem raug cais raws li transverse thiab longitudinal. Transverse nthwv dej propagate perpendicular mus rau kev taw qhia ntawm kev co ntawm qhov nruab nrab, thaum longitudinal nthwv dej propagate parallel mus rau cov kev taw qhia ntawm kev co.

Ondas electromagnéticas

Electromagnetic nthwv dej propagate yam tsis xav tau cov khoom nruab nrab. Cov nthwv dej no tuaj yeem nthuav tawm hauv lub tshuab nqus tsev, vim lawv tsis xav tau qhov nruab nrab elastic xa mus.

Piv txwv ntawm electromagnetic waves

• Ondas de radio
• Ondas de televisión
• Luz visible
• Radiación infrarroja
• Radiación ultravioleta
• Radiación X
• Radiación gamma

Electromagnetic nthwv dej yog tus cwj pwm los ntawm muaj hluav taws xob thiab sib nqus teb uas oscillate perpendicular rau ib leeg thiab perpendicular mus rau cov kev taw qhia ntawm yoj propagation.

Qhov sib txawv ntawm cov tshuab tsis muaj zog thiab cov hluav taws xob tsis zoo

Mechanical waves thiab electromagnetic waves muaj ntau qhov sib txawv:

• Mechanical nthwv dej xav tau cov khoom nruab nrab kom nthuav tawm, thaum electromagnetic tsis tsis muaj.
• Mechanical tsis muaj peev xwm ua tau transverse los yog longitudinal, thaum tag nrho cov electromagnetic tsis yog transverse.
• Electromagnetic nthwv dej propagate ntawm qhov ceev tsis tu ncua (300.000 km / s), thaum qhov ceev ntawm kev nthuav tawm ntawm cov tshuab tsis muaj zog nyob ntawm qhov nruab nrab uas lawv nthuav tawm.
• Electromagnetic nthwv dej tuaj yeem cuam tshuam nrog cov khoom siv hluav taws xob, thaum lub tshuab hluav taws xob tsis muaj peev xwm.

Xaus lus

Hauv kev xaus, mechanical waves thiab electromagnetic waves yog ob hom nthwv dej uas muaj cov khoom sib txawv. Thaum lub tshuab hluav taws xob xav tau cov khoom siv nruab nrab kom nthuav tawm, cov hluav taws xob hluav taws xob tuaj yeem nthuav tawm hauv lub tshuab nqus tsev. Tsis tas li ntawd, electromagnetic tsis muaj cov yam ntxwv tshwj xeeb, xws li muaj peev xwm cuam tshuam nrog cov khoom siv hluav taws xob.
