Cov electromagnetic spectrum yog qhov txuas ntxiv ntawm txhua tus electromagnetic tsis teem caij raws zaus thiab wavelength. Lub hnub, lub ntiaj teb, thiab lwm lub cev radiates electromagnetic lub zog ntawm qhov sib txawv wavelengths. Electromagnetic lub zog dhau los ntawm qhov chaw ntawm qhov ceev ntawm lub teeb nyob rau hauv daim ntawv ntawm sinusoidal nthwv dej.

Tsis tas li ntawd, lub electromagnetic spectrum yooj yim txhais yog dab tsi?

Txhais ntawm electromagnetic spectrum .: tag nrho ntau ntawm wavelengths lossis frequencies ntawm electromagnetic tawg txuas ntawm gamma rays mus rau lub xov tooj cua ntev tshaj plaws nthwv dej thiab suav nrog lub teeb pom kev.

electromagnetic spectrum ua haujlwm li cas? 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 yoj yog tsim. Cov electrons nyob rau hauv cov atoms no ces nyob rau hauv lub zog siab.

Tom qab ntawd, lo lus nug yog, qhov piv txwv ntawm electromagnetic spectrum yog dab tsi?

Tag nrho electromagnetic spectrum , los ntawm qhov qis tshaj mus rau qhov siab tshaj plaws (ntev tshaj plaws mus rau luv tshaj wavelength), suav nrog txhua lub xov tooj cua nthwv dej (piv txwv li, xov tooj cua lag luam thiab TV, microwaves, radar), infrared hluav taws xob , pom lub teeb, ultraviolet hluav taws xob , X-rays, thiab gamma rays.

Qhov twg yog qhov zoo tshaj plaws txhais ntawm electromagnetic zog?

Electromagnetic (EM) hluav taws xob yog ib daim ntawv ntawm zog uas yog nyob ib ncig ntawm peb thiab siv ntau hom, xws li xov tooj cua tsis, microwaves, X-rays thiab gamma rays. Hnub ci kuj yog ib daim ntawv ntawm EM zog , tab sis pom lub teeb tsuas yog ib feem me me ntawm EM spectrum, uas muaj ntau yam ntawm electromagnetic wavelengths.
