Qhov zaus ntawm nthwv dej yog qhov sib npaug ntawm nws qhov wavelength. Qhov ntawd txhais tau hais tias nthwv dej uas muaj zaus muaj lub wavelength luv, thaum nthwv dej nrog ib zaus tsis tshua muaj wavelength ntev.

Yuav ua li cas lub wavelengths muaj zog qis dua?

Qhov ntev ntawm lub wavelength qhia li cas? (Short wavelengths muaj zog ntau dua, hos ntev wavelengths muaj tsawg zog.) 4. UV hluav taws xob muaj lub wavelength luv luv, luv dua li pom lub teeb.

Yuav ua li cas yoj twg muaj qhov ntev tshaj plaws wavelength tab sis qis tshaj zaus?

Ntawm txhua hom hluav taws xob hluav taws xob hluav taws xob, xov tooj cua nthwv dej muaj qhov qis tshaj plaws thiab qhov ntev tshaj plaws wavelength. Cov huab cua ntawm lub ntiaj teb yog pob tshab rau xov tooj cua tsis muaj wavelengths ntawm ob peb millimeters mus txog nees nkaum metres.

Yuav ua li cas wavelength tsawg zaus muaj?

Low zaus (LF) yog ITU tsim rau xov tooj cua zaus (RF) nyob rau hauv qhov ntau ntawm 30–300 kHz. Txij li thaum nws cov wavelengths nyob ntawm 10-1 km, feem, nws tseem hu ua kilometer band lossis kilometer yoj. LF xov tooj cua tsis tshua muaj teeb liab attenuation, ua rau lawv haum rau kev sib txuas lus nyob deb.

Puas ntev wavelength txhais tau tias ceev dua?

Ntshai luv txav nrawm dua thiab muaj zog dua, thiab nthwv dej ntev dua tawm mus qeeb dua thiab muaj zog tsawg. Ib sab ntawm qhov sib txawv frequencies thiab lengths ntawm lub teebnthwv dej, lawv kuj muaj qhov sib txawv.
