NTAUB NTAWV GAMMA RAYS
Tsis zoo li optical teeb thiab x - rays , gamma rays tsis tuaj yeem ntes thiab cuam tshuam los ntawm iav. Gamma - ray wavelengths luv heev li lawv ua tau dhau los ntawm qhov chaw nyob rau hauv lub atom ntawm ib tug detector. Gamma - ray detectors feem ntau muaj densely packed crystal blocks.
Yog li ntawd, tib neeg puas tuaj yeem pom X rays thiab gamma rays?
Teb thiab piav qhia: Tib neeg ua tsis tau saib x - rays los yog gamma rays . Tib neeg tsuas muaj peev xwm saib Lub teeb nyob rau hauv lub teeb pom kev ntawm lub electromagnetic spectrum.
Tsis tas li ntawd, gamma rays kuaj tau li cas? Gamma - rays yog kuaj pom los ntawm kev soj ntsuam cov teebmeem uas lawv muaj rau qhov teeb meem. A gamma -ray tuaj yeem ua ob peb yam yooj yim nrog teeb meem. Nws tuaj yeem sib tsoo nrog lub tshuab hluav taws xob thiab tawm mus zoo li lub pob billiard (Compton scatter) lossis nws tuaj yeem thawb lub tshuab hluav taws xob mus rau qib siab zog (photoelectric ionization).
Ntawm no, X rays thiab gamma rays zoo ib yam?
Qhov sib txawv tseem ceeb ntawm gamma rays thiab X - rays yog li cas lawv raug tsim. Gamma rays keeb kwm los ntawm cov txheej txheem daws teeb meem ntawm ib qho kev zoo siab nucleus ntawm radionuclide tom qab nws dhau los ntawm cov hluav taws xob tawg thaum X - rays yog tsim thaum electrons ntaus ib lub hom phiaj los yog thaum electrons rearrange nyob rau hauv ib tug atom.
Peb puas raug gamma rays?
Ntuj tshwm sim gamma - rays muab ib puas-tam sim no, heev low-level qhov chaw nphav rau hluav taws xob , tab sis qhov kev tshawb fawb txog kev kis kab mob loj heev no qhia tias txawm tias nyob rau theem qis heev no muaj kev pheej hmoo me me rau kev noj qab haus huv.

Koj puas tuaj yeem siv kev txhaum thiab cos ntawm cov duab peb sab tsis zoo?
Xav txog lwm daim duab peb sab uas tsis yog txoj cai, sau npe raws li qhia nrog sab ntev x thiab y. Peb tuaj yeem muab tau ib txoj cai muaj txiaj ntsig uas tsuas muaj cov haujlwm cosine xwb. Txoj cai ntawm cosines tuaj yeem siv los nrhiav kev ntsuas ntawm lub kaum sab xis lossis ib sab ntawm daim duab peb sab uas tsis yog txoj cai yog peb paub: peb sab thiab tsis muaj kaum
Peb puas tuaj yeem siv Newton txoj cai thib peb rau lub zog gravitational?
Yog lawm, Newton txoj cai thib peb yog siv tau rau lub zog gravitational. Yog li ntawd, qhov no txhais tau hais tias thaum peb lub ntiaj teb exerts ib lub zog ntawm attraction ntawm ib yam khoom, ces cov khoom kuj exerts ib tug sib npaug zog rau lub ntiaj teb, nyob rau hauv lub opposite direction. Yog li peb tuaj yeem hais tias koj tuaj yeem siv Newton txoj cai thib peb rau lub zog gravitational
Puas tuaj yeem gamma rays mus los ntawm qhov chaw khoob?
Txhawm rau teb cov lus nug no luv luv, yog gamma rays taug kev hauv lub tshuab nqus tsev. Gamma rays yog electromagnetic yoj, zoo li lub teeb
Qhov twg muaj ntau zaus X rays lossis gamma rays?
X-rays muaj luv wavelengths (siab zog) dua UV nthwv dej thiab, feem ntau, ntev wavelengths (qis zog) dua gamma rays
Cov xuab zeb thiab dej puas tuaj yeem sib cais pom?
Kev piav qhia: Kev lim dej ua haujlwm zoo tshaj plaws yog tias cov ntsiab lus tsis yaj hauv cov kuab tshuaj. Piv txwv li, xuab zeb thiab dej tuaj yeem sib cais los ntawm kev pom vim tias ob qho tib si tsis yaj nrog ib leeg. Txawm li cas los xij, cov suab thaj thiab dej yuav tsis raug cais los ntawm kev pom thaum lawv yaj nrog ib leeg
