A steradian yog siv los ntsuas "lub kaum ntse ntse " tib yam li tus radian cuam tshuam nrog lub voj voog ntawm lub voj voog: Ib Radian "txiav tawm" qhov ntev ntawm ib lub voj voog lub voj voog sib npaug rau lub vojvoog. equal to (radius)2. Lub npe steradian yog tsim los ntawm Greek stereos rau "khoom" thiab radian.
Koj txhais li cas steradian?
Steradian, chav tsev ntawm lub kaum ntse ntse ntsuas hauv International System of Units (SI), txhais tau tias yog lub kaum sab xis ntawm ib tus kheej subtended los ntawm ib feem ntawm qhov chaw uas nws cheeb tsam sib npaug rau lub square ntawm sphere's radius.
Dab tsi yog steradian hauv chav kawm physics 11?
Steradian yog ib chav ntsuas rau cov kaum ntse ntse. Steradian yog lub kaum sab xis subtended, nyob rau hauv nruab nrab ntawm ib tug kheej kheej, los ntawm ib tug nto uas nws loj ntawm cheeb tsam yog sib npaug zos rau square ntawm lub vojvoog ntawm tus kheej. Lub kaum sab xis ntawm ib tug kheej kheej ntawm nws qhov chaw yog 4. steradians.
Tus nqi ntawm 1 steradian yog dab tsi?
Definition. Lub steradian tuaj yeem txhais tau tias yog lub kaum sab xis uas tau muab tso rau ntawm qhov chaw nruab nrab ntawm ib chav tsev los ntawm ib cheeb tsam ntawm nws qhov chaw. Rau qhov dav dav ntawm lub vojvoog r, ib feem ntawm nws qhov chaw nrog thaj tsam A=r2 subtends ib qho steradian ntawm nws qhov chaw.
Yuav siv lub kaum sab xis yog dab tsi?
Nyob rau hauv geometry, lub kaum ntse ntse (cim: Ω) yog ntsuas tus nqi ntawm qhov kev pom los ntawm qee qhov tshwj xeeb uas cov khoom muab npog. Qhov ntawdyog, nws yog ib qho kev ntsuas ntawm qhov loj npaum li cas cov khoom tshwm rau tus neeg soj ntsuam saib los ntawm qhov ntawd.
