Faahfaahinta casharka

Natiijada casharka

Waxaan sharxi karaa waxa iftiinka cad yahay, iyo sababta loo soo saari karo qaybta iftiinka ee la arki karo (visible spectrum) oo ka timaada iftiinka cad.

Hordhac

Darsigani waxa loogu yeedhaa "jeegaan la arki karo (visible spectrum)" waana qayb ka mid ah cutubka "samaynta sawirada (Making Images)". Kahor intaadan daawashadan bilaabin, waa inaad hore u ogaatid in iftiinka cad (white light) uu yahay iftiin caadi ah oo aad ku aragtid nolosha maalinlaha ah.

Muuji qoraalka
White light from the Sun and light bulbs consists of light of all the colours in the visible light spectrum (a rainbow). A transparent triangular prism can split up sunlight into a visible light spectrum. The visible light spectrum shows the range of colours that light can have. Cone cells in the eye detect colour. There are 3 kinds (R, G and B); each is sensitive to a range of colours of light. The colour we see depends on which cone cells are triggered to send a signal to the brain.

Imtixaannada

  1. 1. Qof ayaa haysta shay uu si cad u arki karo dhexdiisa. Shaygu wuxuu sii gudbiyaa iftiinka, sidaas darteed waxaa loo tilmaami karaa inuu yahay...

    • Jawaabta saxda ah:mid iftiinka si buuxda u gudbiya (transparent).
    • mid iftiinka qayb ka gudbiya (translucent).
    • mid iftiinka gudbin (opaque).
    • mid aan la arki karin (invisible).

  2. 2. Intee nooc oo unugyo cone ah ayaa ku jira isha qofka leh aragga midabka oo dhammaystiran?

    • 0
    • 1
    • 2
    • Jawaabta saxda ah:3

  3. 3. Mid ka mid ah kuwan soo socda ayaa sharxaya sababta aan ugu aragno inta badan midabbo cawl (shades of grey) marka iftiinku yaraado?

    • Isirka (pupil) wuxuu weynaadaa marka iftiinku yaraado.
    • Unugyada rod (rod cells) si fiican ugama shaqeeyaan iftiin yar.
    • Jawaabta saxda ah:Unugyada cone (cone cells) si fiican ugama shaqeeyaan iftiin yar.
    • Unugyada cone (cone cells) dhamaantood waxay noqdaan kuwo isku xasaasiyad (sensitivity) leh marka iftiinku yaraado.

  4. 4. Shaashada talefoonka gacanta waxay muujinaysaa moos jaalle ah. Kee ayaa qeexaya sida ay u samayso?

    • Shaashadu waxay ku jirtaa dheeha jaalle ah.
    • Shaashadu waxay leedahay nalal jaalle oo yaryar, kuwaas oo la shido.
    • Jawaabta saxda ah:Shaashadu waxay muujinaysaa laba midab oo iftiin ah, midna ma aha jaalle.
    • Shaashadu waxay kala qaybisaa iftiinka cad oo waxay muujinaysaa midabka jaallaha ah.

  1. 1. Qaanso roobaadku wuxuu muujinayaa midabada iftiinka cad ee la kala saari karo. Waxay had iyo jeer isku hannaanka yimaadaan. Tan waxaa loo yaqaan iftiinka muuqda ee...

    • xariijimaha.
    • qalabka.
    • heerka.
    • miisaanka.
    • Jawaabta saxda ah:spectrum-ka (spectrum).

  2. 2. Jaantusku wuxuu muujinayaa qaab 3D ah oo la yiraahdo __________. Marka qaabkan laga sameeyo muraayad ama balaastiig cad, wuxuu kala qaybin karaa iftiinka cad midabadiisa kala duwan.

    • polygon
    • pyramid
    • triangle
    • tetrahedron
    • Jawaabta saxda ah:triangular prism

  3. 3. Mid ka mid ah weedhahan soo socda ayaa sharxaya sida qaanso-roobaadka loo sameeyo?

    • Dhibic kasta oo roob ah waxay sameysaa dhammaan midabada iftiinka.
    • Dhibco roob oo kala duwan ayaa sameeya midabo iftiin oo kala duwan.
    • Jawaabta saxda ah:Dhibcaha roobku waxay kala qaybiyaan iftiinka cad (white light) dhammaan midabadiisa.
    • Dhibcaha roobku waxay nuugaan (absorb) qaar ka mid ah midabada iftiinka cad, laakiin ma nuugaan midabada qaanso-roobaadka.

  4. 4. Waa kee mid ka mid ah kuwan soo socda oo u ekaan kara iftiin cad (white light) marka isku mar indhahaaga soo gala?

    • isku darka iftiin cas (red) iyo cagaar (green) oo leh dhalaal isku mid ah
    • Jawaabta saxda ah:isku darka iftiin cas, cagaar iyo buluug (blue) oo leh dhalaal isku mid ah
    • isku darka iftiin cas, jaalle (yellow) iyo buluug oo leh dhalaal isku mid ah
    • isku darka dhammaan midabada iftiinka la arki karo (visible light) oo leh dhalaal isku mid ah

  5. 5. Qofku markuu daawado shaashadda telefishanka oo uu ku arko midab cyan, oo ah midab labaad oo iftiinka ah, kee baa ka mid ah hadalladan ku habboon?

    • Midabka cyan kuma soo baxo qaanso roobaadka.
    • Iftiinka shaashadda waxaa qaada unugyada R ee isha qofka.
    • Jawaabta saxda ah:Iftiinka shaashadda waxaa qaada unugyada G ee isha qofka.
    • Iftiinka shaashadda waxaa qaada unugyada B ee isha qofka.
    • Calanka maskaxda loo diro waa isku mid marka uu arko shay cyan ah.
