Gamma rays muaj lub zog siab tshaj plaws, qhov luv tshaj plaws wavelengths, thiab ntau zaus. Xov tooj cua nthwv dej, ntawm qhov tod tes, muaj lub zog qis tshaj plaws, qhov ntev tshaj plaws wavelengths, thiab qis tshaj zaus ntawm txhua hom hluav taws xob EM.

Koj paub li cas yoj twg muaj zaus tshaj?

Wave zaus ntsuas tau los ntawm suav cov crests (cov ntsiab lus siab) ntawm cov nthwv dej uas dhau qhov taw tes ruaj khov hauv 1 thib ob lossis qee lub sijhawm. Tus lej siab dua, qhov zaus ntawm nthwv dej ntau dua.

Dab tsi yog qhov hluav taws xob ntau zaus hluav taws xob?

High frequency (HF) yog ITU tsim rau ntau yam ntawm xov tooj cua zaus electromagnetic waves (xov tooj cua tsis muaj zog) nruab nrab ntawm 3 thiab 30 megahertz (MHz) Nws tseem hu ua decameter band lossis decameter nthwv dej raws li nws qhov wavelengths ntawm ib mus rau kaum decameters (kaum mus rau ib puas meters).

Puas yog electromagnetic nthwv dej muaj ntau zaus?

Lub cheeb tsam microwave ntawm electromagnetic (EM) spectrum feem ntau yog suav tias yog sib tshooj nrog lub siab tshaj plaws zaus (shortest wavelength) xov tooj cua tsis muaj. Raws li qhov xwm txheej rau txhua qhov EM nthwv dej, microwaves taug kev hauv lub tshuab nqus tsev ntawm qhov ceev ntawm lub teeb.

Vim li cas yoj thiaj li muaj ntau zaus?

Cov ntsuas rau qhov ntsuas no yog Hertz (hz). Yog li, yog tias lub wavelength ntawm lub teeb nthwv dej luv dua, txhais tau hais tias qhov zaus yuav siab dua vim ib lub voj voog tuaj yeem dhau sijhawm luv dua. Qhov no txhais tau tias ntau lub voj voog tuaj yeem dhau los ntawm qhov teeb tsa hauv 1 thib ob.
