Khoom tsim lub cev microwave
Microwave yog hom hluav taws xob electromagnetic. Zoo li high-zaus hluav taws xob tsis muaj hluav taws xob, nws yog tsim los ntawm kev hloov pauv txhua ntu ntawm qhov hluav taws xob thiab sib nqus cov zog hluav taws xob hauv hluav taws xob hauv hluav taws xob hluav taws xob. Microwave hluav taws xob feem ntau yog hais txog hluav taws xob hluav taws xob nrog qhov ceev ntawm 300 txog 300,000 MHz thiab ib nthwv dej qis dua 1 m. Raws li nws qhov ntev ntom nti, microwave tuaj yeem muab faib ua decimeter yoj, centimeter wave thiab millimeter yoj. Yuav luag txhua lub tshuab hluav taws xob ultraviolet rau lub lag luam yog microwave-zoo siab heev, thiab kev ua haujlwm hauv microwave rau lub sijhawm ntev yuav ua rau muaj kev phom sij rau tib neeg lub cev.
