Nyob Zoo Sawv Daws!

Zoo siab txais tos rau lwm qhov qhia los ntawm Let's Innovate.

Hauv cov lus qhia no kuv yuav coj koj los ua koj tus kheej qhov pheej yig interferometer tiag tiag. Qhov tseem ceeb ntawm qhov "pheej yig tiag" vim tias muaj ntau yam khoom siv kim heev nyob rau ntawd koj tuaj yeem yuav tab sis los ntawm kev ua raws cov lus qhia no koj yuav tuaj yeem ua koj tus kheej li interferometer uas yuav raug nqi koj tsis muaj dab tsi! Thiab tsis txawm xav tau sijhawm ntau los teeb tsa!

Qhov haujlwm no yog ib feem ntawm kuv nkag mus rau CAIE Science Project. Kuv vam tias koj pom nws nthuav.

Tsis paub tias interferometer yog dab tsi? Tsis muaj teeb meem, tsuas yog txheeb xyuas qhov no, qhov no yuav ua rau koj mob siab tiag tiag txog cov no:

Kuj sau npe rau peb cov channel:

Peb yuav nyiam qee qhov kev txhawb nqa ntawm cov channel. Ua tsaug!

Khoom siv

Nov yog cov khoom kuv siv:

• 1 ntsuab laser pointer
• ua si ua si
• 2 tsom iav me me
• 1 daim ntawv hardboard
• qee daim ntoo (xaiv tau)
• Pob tshab yas yas npog.
• Daim kab xev ob tog

Kauj ruam 1: Tau txais Laser

Kuv qiv lub laser los ntawm ib tus phooj ywg. Nws yog tus taw qhia laser uas kim thiab muaj lub hom phiaj zoo tab sis koj yuav tsum tsis txhob kim. Cov uas pheej yig tshaj qhia los ntawm ebay tseem yuav ua haujlwm tau zoo heev.

Zoo li qhov no:

Txawm tias cov keychain me me yuav ua haujlwm.

Kuv yuav hais kom xaiv lub laser taw qhia ntsuab, tab sis lwm yam xim tseem yuav ua haujlwm yam tsis muaj teeb meem.

Lub laser taw qhia tau cylindrical nyob rau hauv cov duab thiab khaws dov hla yog li kuv siv qee cov roj hmab band thiab khi nws rau ib daim ntoo kom ntxiv qee qhov nce. Koj tuaj yeem siv txhua yam rau kev tiv thaiv nws los ntawm dov zoo li duab los qhia.

Kauj Ruam 2: Txheeb Thawj Daim iav

Txog ntawm daim iav, Kuv nyuam qhuav tawg ib daim iav me me (ua tib zoo saib) ua 2 daim me me uas siv tau thiab tom qab ntawd muab lo rau ntawm qee cov ntoo kom ruaj khov.

Tom qab ntawd kuv tau muab lub hardboard tso rau ntawm kuv tus pointer laser. Tom qab ntawd kuv tso qee qhov ua si-ua khob noom cookie ncaj qha pem hauv ntej ntawm tus pointer laser. Daim iav tau muab tso rau ntawm lub khob noom ua si tam sim no.

Cov kauj ruam tom ntej yog tig lub laser taw qhia thiab tinker nrog daim iav kom lub nqaj ntawm lub teeb pom kev ncaj qha rov qab rau hauv lub lens ntawm lub laser.

Koj yuav pom tias kev siv ua si-ua khob noom cookie pab tau ntau yam vim tias nws mos thiab cov nqaij mos tau yooj yim tau deformed hauv qab qhov hnyav.

Kauj Ruam 3: Lub Beam Splitter

Qhov tseem ceeb tshaj plaws ntawm Michelson Interferormeter yog kab tias nws yog cov kab sib cais. Beam splitters yog kim heev thiab tsis yooj yim nkag tau rau txhua qhov chaw, yog li kuv tau ua kuv tus kheej cov khoom tawg.

Lub splitter yog daim npog CD pheej yig. Muab nws tso rau ntawm kwv yees li 45 degree kaum ntawm lub laser thiab daim iav nrog qee daim kab xev ob tog. Xyuas kom tseeb tias cov nqaj sib faib hla lub hardboard vim tias daim iav thib ob yuav tsum tau muab tso rau ntawm daim tawv tawv.

Daim npog CD ua haujlwm tsis muaj teeb meem!

Kauj Ruam 4: Txheeb Daim Duab Thib Ob

Nov yog qhov ua kom yuam kev, tab sis siv tib cov txheej txheem ntawm lub zog ua si-ua khob noom cookie, koj tuaj yeem yooj yim dhau los.

Muab qee qhov ua si-ua khob noom cookie coj mus rau qhov sib cais. Tam sim no tso daim iav thib ob ntawm qhov ua si-khob noom cookie. Ib zaug ntxiv koj yuav tsum kho daim iav, tab sis lub sijhawm no lub teeb pom kev xav tau ncaj qha rov qab rau ntawm qhov chaw uas muaj lub teeb pom kev zoo ntawm daim npog CD (beam splitter).

Thaum koj tau ua tiav cov kauj ruam no koj tau npaj siv qhov ntsuas no!

Kauj Ruam 5: Cov Ntsiab Lus

Coj koj lub teeb mus rau chav tsaus thiab ua lub zog laser. Saib ze ze ntawm kev cuam tshuam (nyob ib puag ncig rau thawj kab ntawm lub teeb piv txwv li lub laser thiab thawj daim iav ib feem, thiab ncaj qha rau pem hauv ntej ntawm daim iav thib ob). {Koj yuav xav tau phab ntsa kom ze rau ntawm txoj kev ntawm kev taw qhia ntawm kev cuam tshuam}.

Koj yuav pom lub teeb thiab tsaus voj. Nws muaj qhov zoo sib xws rau cov dej ripples tsis yog nws? Qhov ntsuas no siv lub teeb yoj zog los ntsuas qhov tseeb.

Txheeb xyuas nplooj ntawv no kom paub ntau ntxiv:

Tsuas yog kov daim iav maj mam cuam tshuam tus qauv yuav hloov pauv. Koj tseem tuaj yeem tsuas yog hais lus, thiab koj yuav pom kev hloov pauv ntawm tus qauv cuam tshuam. Qhov ntsuas no yog qhov rhiab heev thiab nws tau siv los tshawb pom lub ntiajteb txawj nqus.
