X-rays yog tsim los ntawm kev foob pob hlau lub hom phiaj los ntawm kev kub ceev electrons.
Qhov twg ntawm electromagnetic spectrum yog tsim los ntawm kev foob pob?
b) X-rays yog tsim los ntawm kev foob pob ib lub hom phiaj hlau nrog high-speed electrons.
Xrays yog dab tsi?
X-ray, hluav taws xob hluav taws xob hluav taws xob ntawm lub wavelength luv luv thiab siab zaus, nrog wavelengths li ntawm 10- 8 rau 10 −12 meter thiab sib txuas zaus los ntawm kwv yees li 10 16 rau 10 20hertz (Hz).
Yuav ua li cas thiaj tsim tau cov electromagnetic spectrum?
Electromagnetic radiation yog tsim thaum twg ib qho nqi them, xws li electron, hloov nws qhov nrawm-i.e., thaum twg nws tau nrawm lossis qeeb. Lub zog ntawm cov hluav taws xob hluav taws xob hluav taws xob yog li tsim los ntawm cov khoom siv hluav taws xob thiab yog li poob los ntawm nws.
Dab tsi oscillates hauv electromagnetic spectrum?
Electromagnetic nthwv dej yog transverse nthwv dej. Qhov ntawd txhais tau hais tias hluav taws xob thiab sib nqus teb hloov(oscillate) hauv lub dav hlau uas yog perpendicular rau kev taw qhia ntawm kev nthuav tawm ntawm nthwv dej. Tsis tas li ntawd nco ntsoov tias hluav taws xob thiab sib nqus teb nyob rau hauv EM nthwv dej kuj yog nyob rau ib leeg.
