Qhov sib txawv ntawm cov hluav taws xob hluav taws xob muaj nyob rau hauv electromagnetic spectrum muaj xov tooj cua , microwaves, infrared tsis, pom lub teeb, ultraviolet hluav taws xob, X-rays, thiab gamma rays. Ib feem ntawm electromagnetic spectrum uas peb tuaj yeem pom yog qhov pom lub teeb spectrum.
Hauv qhov no, 7 hom electromagnetic vuag yog dab tsi?
Txawm hais tias kev tshawb fawb feem ntau faib EM nthwv dej rau hauv xya hom, txhua yam yog qhov tshwm sim ntawm tib yam tshwm sim
- Xov tooj cua Waves: Instant Communication.
- Microwaves: Cov ntaub ntawv thiab cua sov.
- Infrared Wave: Invisible Thaum tshav kub kub.
- Pom Teeb Rays.
- Ultraviolet waves: Lub teeb muaj zog.
- X-rays: Penetrating Radiation.
- Gamma Rays: Nuclear Zog.
Kuj Paub, yuav ua li cas electromagnetic tawg? Electromagnetic hluav taws xob yog ib daim ntawv ntawm lub zog. Electromagnetic hluav taws xob yog tsim thaum lub atom absorbs zog. Lub zog absorbed ua rau ib los yog ntau dua electrons hloov lawv lub zos nyob rau hauv lub atom. Thaum lub electron rov qab mus rau nws qhov qub chaw, ib electromagnetic vuag yog ua.
Ntawm no, hom hluav taws xob hluav taws xob twg muaj qhov ntev tshaj plaws wavelength?
Xov tooj cua
Puas yog hluav taws xob hluav taws xob muaj kev phom sij?
Tsis muaj qhov tsis ntseeg tias qhov luv luv raug rau cov qib siab heev electromagnetic teb tau phom sij rau kev noj qab haus huv. Txawm hais tias kev tshawb fawb dav dav, los txog niaj hnub no tsis muaj pov thawj los xaus qhov kev cuam tshuam rau qib qis electromagnetic teb yog phom sij rau tib neeg noj qab haus huv.

Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
Dab tsi yog qhov txawv ntawm tus kws tshaj lij hluav taws xob thiab tus kws tshaj lij hluav taws xob?
Qhov sib txawv tseem ceeb ntawm cov kws tshaj lij hluav taws xob thiab cov kws tshaj lij xov tooj cua yog lawv cov qib kev kawm.Lawv yuav tau dhau ob qho kev xeem ntawv pov thawj RN thiab theradiology cov kws saib xyuas neeg mob daim ntawv pov thawj xws li ib tus tswj hwm los ntawm Lub Koom Haum rau Radiologic & ImagingNursing
Kev sib raug zoo ntawm hluav taws xob thiab hluav taws xob teb yog dab tsi?
Electric teb yog txhais raws li lub zog hluav taws xob ib chav tsev nqi. Cov kev taw qhia ntawm lub teb yog coj mus rau qhov kev taw qhia ntawm lub zog nws yuav ua rau ib tug zoo kuaj nqi. Cov hluav taws xob hluav taws xob yog radially sab nraud los ntawm tus nqi zoo thiab radially mus rau qhov tsis zoo ntawm tus nqi
