Microwaves poob rau hauv thaj tsam ntawm EM spectrum nruab nrab ntawm xov tooj cua thiab lub teeb infrared.

microwaves pom nyob qhov twg ntawm electromagnetic spectrum?

MICROWAVE BANDS

Microwaves yog ib feem lossis "band" pom ntawm qhov zaus siab dua ntawm xov tooj cua spectrum, tab sis lawv feem ntau txawv ntawm xov tooj cua vim ntawm cov technologies siv los nkag rau lawv.

YYuav ua li cas wavelength yog microwaves?

cheeb tsam microwave txuas ntxiv los ntawm 1, 000 txog 300, 000 MHz (los yog 30 cm mus rau 1 mm wavelength)Txawm hais tias microwaves tau xub tsim thiab kawm hauv 1886 los ntawm Hertz, lawv. Daim ntawv thov tswv yim yuav tsum tau tos lub invention ntawm tsim generators, xws li cov klystron thiab magnetron.

Cov piv txwv ntawm microwaves hauv cov electromagnetic spectrum yog dab tsi?

Microwaves yog electromagnetic nthwv dej uas muaj qhov ntev wavelengths thiab tsawg zaus. Lawv siv rau microwave ncu, xov tooj ntawm tes, thiab radar. Lub xov tooj ntawm tes encodes lub suab ntawm tus hu lub suab hauv microwaves los ntawm kev hloov qhov zaus ntawm nthwv dej.

Yuav ua li cas ua microwaves electromagnetic spectrum?

Microwaves yog tsim nyob rau hauv qhov cub los ntawm ib lub raj hluav taws xob hu ua magnetron. Cov microwaves tau pom nyob rau hauv cov hlau sab hauv ntawm qhov cub uas lawv nqus los ntawm cov zaub mov.
