Faahfaahinta casharka

Natiijada casharka

Waxaan sharxi karaa sida iftiinka u dhex maro godka yar si uu u soo saaro sawir kamarada godka yar.

Hordhac

Salaan caafimaad, waxaan ahay Dr. George. Casharkani wuxuu ku saabsan yahay kamarad daloolin (pinhole camera), kaas oo qayb ka mid ah cutubka samaynta sawiraanka (making images). Maanta waxaad samayn doontaa oo aad tijaabin doontaa (experiment) nooc kamarad ah, laakiin ka hor inta aanan bilow, waxaad horey u ogaatay in iftiinku uu safar ku dhex maro hawada iyo walxaha cad.

Muuji qoraalka
A pinhole camera is an empty, closed box with a tiny hole on the front face and a screen on the back face. Light moves in straight lines from a light source, through the pinhole, to the screen at the back of a pinhole camera. Light from each different point on the object falls on a different single point on the screen, forming the image. The image produced by a pinhole camera is dim and inverted. Adding more holes produces multiple images. Making the hole larger makes the image brighter but blurred. More light passes through the hole in more directions.

    • Waxay u ogolaanaysaa in iftiin aan dhex gudbin.
    • Waxay u ogolaanaysaa in iftiin dhex maro oo aad si cad u aragto dhinaca kale.
    • Waxay u ogolaanaysaa in iftiin dhex maro oo ay beddesho midabka iftiinka.
    • Jawaabta saxda ah:Waxay u ogolaanaysaa in iftiin qaar dhex maro, laakiin aadan si cad u arki karin dhinaca kale.

  2. 2. Mid ka mid ah kuwan soo socda ayaa qeexaya shay ifaya (luminous object)?

    • Jawaabta saxda ah:shay iftiin sii daaya

    • shay iftiin nuuga
    • shay iftiin ka celiya sida muraayaddu u qabato

  3. 3. Jaantusyada, waxaan sawiri karnaa fallaaro si aan u muujinno jihada iftiinku socdo, iyo halka iftiinku ka yimaado iyo halka uu ku socdo. Waa maxay magaca fallaarahan?

    • laasarka (laser beams)
    • fallaaraha iftiinka (light arrows)
    • beeraha iftiinka (light beams)

    • shay dhab ah
    • shay khiyaali ah
    • Jawaabta saxda ah:matagasho shay dhab ah
    • matagasho shay khiyaali ah

  5. 5. Waa maxay mid ka mid ah weedahan oo had iyo jeer lagama maarmaan u ah inaad aragto shay?

    • Shaygu waa inuu iftiin sameeyo (luminous).
    • Iftiinka agagaarka waa inuu ku dhaco shayga.
    • Iftiinka ka imanaya indhahaaga waa inuu gala shayga.
    • Jawaabta saxda ah:Iftiinka ka imanaya shayga waa inuu gala indhahaaga.

  6. 6. Deeqaamada soo socda midkee baa sharxaya sababta ay sahlan tahay in la arko laambad aan iftiin badnayn banaanka habeenkii marka loo eego maalintii?

    • Iftiinka laambadda iyo iftiinka maalintu waa is baajiyaan.
    • Laambaddu waxay soo saartaa iftiin badan marka ay hareeraheeda mugdi yihiin.
    • Jawaabta saxda ah:Habeenkii waxaa jira farqi (contrast) dheeri ah oo u dhexeeya laambadda iyo hareeraheeda.
    • Maalintii waxaa badan oo iftiinka laambadda ah oo ay nuugaan (absorb) hareeraha.

  1. 1. Ereyga ka mid ah kuwan soo socda, kee baa macnihiisu yahay ‘dul loo rogay’ (turned upside-down)?

    • converted (beddelay)
    • diverted (leexiyay)
    • Jawaabta saxda ah:inverted (dul rogay)
    • reverted (soo celiyay)

  2. 2. Kubad ayaa hawada ku socota iftiinka maalinta. Kubaddu ma aha mid dhalaalaysa mana aha mid madow. Kee ayaa ka mid ah hadalladan ku habboon?

    • Dhibic kasta oo ka mid ah dusha kubadda ayaa sii daaya iftiin.
    • Jawaabta saxda ah:Dhibic kasta oo ka mid ah dusha kubadda ayaa ka tarjumaysa iftiin.
    • Iftiin ka yimaada dhibic kasta oo dusha kubadda ayaa si toos ah u baxa.
    • Jawaabta saxda ah:Iftiin ka yimaada dhibic kasta oo dusha kubadda ayaa u socda jihooyin badan.

  3. 3. Waa kuwee kuwan soo socda kuwa loo baahan yahay kamarad dalool (pinhole camera) si ay u muujiso sawir cad?

    • muraayad (lens)
    • Jawaabta saxda ah:shaashad iftiinka dhex mara (translucent screen) oo ku taal gadaasha kamaradda
    • shaashad iftiinka dhex mara oo ku taal horta kamaradda
    • Jawaabta saxda ah:shay aad u ifaya oo la eego
    • shay laga yaabo inuu ifo ama uusan ifin oo la eego

  4. 4. Ardaygu wuxuu sameeyaa kamarad dalool yar (pinhole camera) oo wuxuu ku sawiraa nalka (bulb). Kadib ardaygu wuxuu weyneeyaa daloolka. Sidee ayay tani u beddeshaa sawirka?

    • wuu weynaadaa
    • wuu yaraadaa
    • wuu caddeeyaa
    • Jawaabta saxda ah:wuu wasakhaysanayaa (blurred)

  5. 5. Kameerad dalool-yar (pinhole camera) waxay sameysaa sawir laambad filaaman ah. Kee ka mid ah isbeddelladan soo socda ayaa ka dhigi doona sawirka mid ka yar?

    • Jawaabta saxda ah:u dhaqaaqista kameerada inay ka sii fogeyso laambadda
    • isticmaalka sanduuq dheer oo loogu talagalay kameerada dalool-yar
    • Jawaabta saxda ah:isticmaalka sanduuq gaaban oo loogu talagalay kameerada dalool-yar

  6. 6. Arday ayaa kamarad dalool-yar (pinhole camera) ku haysta meel gaaban u jirta laambad (filament bulb) oo shidan. Kee ayaa ka mid ah weedhahan soo socda oo sharxaya sababta sawirka laambaddu uga soo baxo shaashadda?

    • Sawirka laambaddu wuxuu ku habboonaadaa daloolka yar wuxuuna ku soo degaa shaashadda.
    • Daloolka yar wuxuu beddelaa jihada fallaadhaha (rays) si ay u sameeyaan sawir.
    • Qayb kasta oo ka mid ah shaashadda waxaa ku dhaca iftiin ka yimid meel kasta oo laambadda ka mid ah.
    • Jawaabta saxda ah:Qayb kasta oo ka mid ah shaashadda waxaa ku dhaca iftiin ka yimid hal meel oo keliya oo laambadda ka mid ah.
