Faahfaahinta casharka

Natiijada casharka

Waxaan sharxi karaa astaamaha sawirrada muraayadda siman (plane mirror), waxaana sawiri karaa jaantusyo muujinaya sida sawirrada loo sameeyo.

Hordhac

Salaan, waxaan ahay Dr. George, casharkani wuxuu ku saabsan yahay 'Reflected Images' oo ah sawirro lagu arkay muraayad fidsan. Waa qayb ka mid ah cutubka 'Making Images' oo ah samaynta sawirrada. Kahor intaadan bilaabin, waa inaad hore uga warqabtaa sida iftiinku u safro iyo waxa ay tahay muraayad fidsan, si aad si fudud ugu fahanto sifooyinka sawirrada iyo sida ay u samysmaan.

Muuji qoraalka
Reflections are the same size as the object, upright, and the same distance behind the mirror as the object is in front. In a plane mirror, reflections appear laterally inverted compared to the object when it is facing us. Mirrors reflect what is in front of them. Reflections are laterally inverted as objects are turned to face a mirror. Reflections are virtual images; they appear where light rays seem to have come from, not where they actually come from. Virtual rays show where light rays appear to have come from; they are drawn as dashed lines.

    • Labada xagal waxay ku yaalliin diyaarado kala duwan.
    • Xagallada waxay ku yaalliin dhinacyo ka soo horjeeda muraayadda (mirror).
    • Xagallada waxay ku yaalliin dhinacyo ka soo horjeeda xariiqda toosan (normal).

    • Iftiinka ku dhacaya shaashadda aad buu u yar yahay.
    • Iftiinka ku dhacaya shaashadda aad buu u iftiimayaa.
    • Jawaabta saxda ah:Iftiinka meel kasta oo laambadda ka mid ah wuxuu ku dhacaa meel kasta oo shaashadda ah.

    • 4 m
    • 6 m
    • Jawaabta saxda ah:8 m

    • Jawaabta saxda ah:Laura
    • Sofia
    • qofna

  3. 3. Arday waxay haysaa warqad ay ku qoran tahay ereyga 'HELLO', sida sawirka ku cad. Waxay u rogtaa dhinac jiifa si ay u wajahdo muraayad. Mid ka mid ah milicsiyada soo socda ayay ku arki doonaan muraayadda?

    • Jawaabta saxda ah:Sawirka koowaad
    • Sawirka labaad
    • Sawirka saddexaad
    • Sawirka afraad

  4. 4. Mid ka mid ah kuwan soo socda ayaa sharxaya milicsiga (reflections) ee muraayadaha lagu arko?

    • Haddii shay uu ku yaallo dhanka midig, sawirkiisu wuxuu ku yaallaa dhanka bidix.
    • Sawirka shaygu wuxuu ka weynaan karaa shayga laftiisa.
    • Sawirka shaygu wuxuu ka yaraan karaa shayga laftiisa.
    • Jawaabta saxda ah:Haddii shay uu ka fog yahay muraayadda, sawirkiisuna wuu ka fog yahay muraayadda.

  5. 5. Kee ka mid ah weedhahan ku saabsan fallaadhaha (rays) iyo sawirada (images) aan dhabta ahayn ayaa sax ah?
