Cov net ntawm ib daim duab khoom yog tsim thaum lub cev muaj zog yog nthuav tawm raws nws cov npoo thiab nws lub ntsej muag tau muab tso rau hauv ib qho qauv hauv ob qhov ntev. Nets ntawm rectangular prism yog ua los ntawm cov duab plaub thiab squares. Siv a net txhawm rau nrhiav thaj chaw saum npoo ntawm ib daim duab plaub prism.
Tom qab ntawd, lub net ntawm ib lub cev yog dab tsi?
Ib tug geometry net yog 2-dimensional puab uas tuaj yeem folded los ua 3-dimensional puab los yog ib qho khoom. Los yog a net yog ib qho qauv ua thaum lub npoo ntawm daim duab peb sab yog nteg tawm tiaj tus uas qhia txhua lub ntsej muag ntawm daim duab.
Ib yam li ntawd, thaj chaw net yog dab tsi? A net yog ib daim duab uas qhia cov npoo thiab ntsej muag ntawm ib qho khoom hauv ob qhov ntev. Koj tuaj yeem xav txog ib net raws li qhov koj yuav tau txais yog tias koj "kho" ib qho khoom. Cov net yog ua los ntawm peb congruent rectangles thiab ob congruent equilateral triangles. Cov thaj chaw saum npoo yog qhov sum ntawm thaj chaw ntawm tsib daim duab.
Ua li no, ua li cas koj kos ib lub voj voog prism net?
Rau ua koj net , koj nco ntsoov tias koj lub thawv yuav tsum muaj tag nrho ntawm 6 sab. Koj txiav txim siab ua a net qhov twg hauv qab yog surrounded los ntawm nws plaub sab thiab ces sab saum toj txuas nrog ib sab. Qhov no net ntawm lub thawv uas koj yog ua kuj hu ua txoj cai rectangular prism , pib a duab plaub lub thawv.
Tus qauv rau saum npoo yog dab tsi?
Peb kuj tuaj yeem sau npe rau ntev (l), dav (w), thiab qhov siab (h) ntawm lub prism thiab siv cov qauv, SA = 2lw + 2lh + 2hw, los nrhiav thaj chaw saum npoo.
Pom zoo:
Qhov ntim ntawm prism yog dab tsi?
Cov mis rau qhov ntim ntawm ib lub prism yog V = Bh, qhov B yog lub hauv paus cheeb tsam thiab h yog qhov siab. Lub hauv paus ntawm prism yog ib daim duab plaub. Qhov ntev ntawm daim duab plaub yog 9 cm thiab qhov dav yog 7 cm
Lub zog dispersive ntawm Prism yog dab tsi?
Lub zog dispersive yog ib qho kev ntsuas ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov siab tshaj plaws thiab qhov qis tshaj plaws uas nkag mus rau lub prism. Qhov no yog qhia nyob rau hauv lub kaum sab xis ntawm 2 huab wavelengths. Qhov ntau dua lub zog dispersive, ntau dua lub kaum sab xis ntawm lawv, thiab vice-versa
Dab tsi yog qhov ntim ntawm daim duab peb sab prism?
Qhov ntim ntawm ib daim duab peb sab prism tuaj yeem pom los ntawm kev sib npaug ntawm lub hauv paus lub sij hawm qhov siab. Ob daim duab ntawm daim duab peb sab prisms hauv qab no qhia txog tib lub mis. Cov mis, feem ntau, yog thaj tsam ntawm lub hauv paus (daim duab peb sab liab hauv daim duab sab laug) lub sij hawm qhov siab, h
Dab tsi yog qhov ntim hauv cubic units ntawm rectangular prism?
Yuav kom nrhiav tau qhov ntim ntawm ib lub prism, muab nws 3 qhov ntev: ntev x dav x qhov siab. Qhov ntim tau qhia hauv cubic units
Tus nqi ntawm dispersive zog ntawm Prism yog dab tsi?
Cov pom wavelengths zoo refrac ntawm cov sib txawv thiab sib cais rau hauv lawv cov xim. Dispersivepower yog ib qho kev ntsuas ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov siab tshaj plaws thiab qis tshaj wavelengths uas nkag mus rau prism. Qhov no yog qhia nyob rau hauv lub kaum sab xis ntawm 2 heev wavelengths
