Txhawm rau txiav txim siab Dispersive zog ntawm prism:
- Tig lub rooj vernier thiaj li poob lub teeb los ntawm lub collimator mus rau ib lub ntsej muag ntawm lub prism thiab tau tshwm sim los ntawm lwm lub ntsej muag.
- Tig lub telescope kom lub slit coincide nrog telescopecross hlau.
- Cov hluav taws xob tawm muaj xim sib txawv.
Ib yam li ntawd, nws yog nug, dab tsi yog lub zog dispersive ntawm prism?
Dispersive zog 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 hauv prism . Qhov loj dua dispersive zog , qhov ntau dua lub kaum sab xis ntawm lawv, thiab vice-versa.
Kuj Paub, dab tsi yog xim prism? Prisms tuaj yeem ua los ntawm txhua yam khoom uas yog pob tshab rau lub wavelengths uas lawv tsim. Cov khoom siv xws li iav, yas, thiab fluorite. Ib tug dispersive prism tuaj yeem siv los rhuav lub teeb rau hauv nws cov constituentspectral xim (cov xim ntawm zaj sawv).
Ntawm no, dab tsi yog tus qauv ntawm dispersive zog?
tus dr) / (dy) yog lub npe hu ua dispersive zog ntawm cov khoom ntawm prism thiab yog denoted los ntawm ω. The dispersive zog ntawm cov khoom ntawm ib tug prism yog txhais raws li qhov piv ntawm angular kev tawg rau ob lub wavelengths (xim) rau qhov sib txawv ntawm qhov nruab nrab wavelength.
Muaj pes tsawg xim muaj nyob rau hauv prism?
COLOR SPECTRUM Cov neeg feem coob tuaj yeem pom tsuas yog xya qhov sib txawv xim nyob rau hauv spectrum: liab, txiv kab ntxwv, daj, ntsuab, xiav, indigo, thiab violet. Ib yam li ib prism tuaj yeem faib lub teeb dawb rau hauv qhov sib txawv xim , yog li lub teeb ntawm cov xim sib txawv tuaj yeem muab ntxiv ua ke ua kom lub teeb dawb.

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
Yuav ua li cas tshwm sim thaum koj sib tov ib tug muaj zog acid nrog ib tug tsis muaj zog puag?
Hom 2: thaum muaj zog acid / base reacts nrog lub hauv paus tsis muaj zog / acid yog hydronium thiab hydroxyl ions tam sim no nyob rau hauv sib npaug amt ces ntsev thiab dej yog tsim thiab lub zog tso tawm uas tsawg tshaj li 57 kj / mole vim lub dissociation ntawm lub tsis muaj zog acid / puag uas feem ntau endothermic
Yuav ua li cas yog qhov tshwm sim uas ib tug poj niam dig muag xim uas yuav ib tug txiv neej uas tsis pom kev zoo yuav muaj xim dig muag me nyuam?
Yog tias tus poj niam uas muaj lub zeem muag zoo li no (heterozygous rau qhov muag tsis pom xim) yuav ib tug txiv neej ib txwm muaj (XY), cov xeeb ceem hauv qab no tuaj yeem xav tau hauv F2 tiam: ntawm cov ntxhais, 50% yog ib txwm muaj thiab 50% yog cov neeg nqa khoom rau cov kab mob; ntawm cov tub, 50% yog xim dig muag thiab 50% yog qhov pom kev zoo
Yuav ua li cas koj pom lub hauv paus cheeb tsam ntawm daim duab peb sab prism?
Ib daim duab peb sab prism muaj peb lub duab plaub sab thiab ob lub ntsej muag daim duab peb sab. Txhawm rau nrhiav thaj tsam ntawm lub kaum sab xis, siv tus qauv A = lw, qhov twg A = thaj tsam, l = ntev, thiab h = qhov siab. Txhawm rau nrhiav thaj tsam ntawm daim duab peb sab, siv cov qauv A = 1/2bh, qhov twg A = thaj tsam, b = puag, thiab h = qhov siab
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
