Natiijada casharka
Waxaan awoodi doonaa inaan sharaxo sida iftiinku uga milicsado muraayadaha, xagasha soo-gaadhista (angle of incidence) iyo xagasha milicsiga (angle of reflection).
Hordhac
Soo dhawoow darsigan. Waa qayb ka mid ah cutubka codka, iftiinka iyo aragga, darsigana waxaa loogu yeedhaa milicsiga iftiinka muraayadaha. Waa inaad hore u taqaan sida iftiinka u safro iyo in muraayaduhu ay iftiinka milicsadaan, laakiin maanta waxaad baran doontaa sida loo cabbiro xaglaha milicsiga iyo sida loo raadraaco laydhka iftiinka.

Imtixaannada
1. Sawirrada soo socda, kee baa si sax ah u muujinaya iftiinka (light rays) ka soo baxaya laambad?
- Jawaabta saxda ah:Sawirka koowaad
- Sawirka labaad
- Sawirka saddexaad
2. Waa kuwee qaybaha (units) ee xaglaha lagu cabbiro?
- mitir
- Jawaabta saxda ah:darajo (degrees)
- milimitir
- mililitir
3. Waa imisa cabbirka xagasha la calaamadeeyay?
- 50°
- Jawaabta saxda ah:90°
- 100°
- 180°
- 360°
4. Qalabkee ka mid ah kuwan soo socda ayaa loo isticmaalaa in lagu cabbiro xaglaha (angles)?
- rulerkii (ruler)
- compaskii (compass)
- Jawaabta saxda ah:protractor-ka (protractor)
- set square-ka (set square)
5. Waa imisa cabbirka xagasha calaamadeysan ee u dhaxaysa labada xariiq ee sawirka ku jira?
- Jawaabta saxda ah:37°
- 43°
- 143°
- 157°
1. Jaantusyada waxay muujinayaan iftiin ka milicsanaya muraayad. Jaantuskee ayaa lagu calaamadeeyay xagasha dhacanka (angle of incidence)?
- Jaantuska koowaad
- Jaantuska labaad
- Jawaabta saxda ah:Jaantuska saddexaad
- Jaantuska afraad
2. Mid ka mid ah kuwan soo socda waa sharciga koowaad ee milicsiga (reflection)?
- xagasha milicsiga (angle of reflection) way ka weyn tahay xagasha soo-gaadhista (angle of incidence)
- Jawaabta saxda ah:xagasha milicsiga waxay la mid tahay xagasha soo-gaadhista
- xagasha milicsiga + xagasha soo-gaadhista = 90°
- xagasha milicsiga + xagasha soo-gaadhista = 180°
3. Waa kuwee kuwaan ah sharciga labaad iyo saddexaad ee milicsiga (reflection)?
- Laamta soo gasha (incident ray) iyo laamta soo noqota (reflected ray) waxay ku yaalliin dhinac isku mid ah ee xariiqda toosan (normal).
- Jawaabta saxda ah:Laamta soo gasha iyo laamta soo noqota waxay ku yaalliin dhinacyo iska soo horjeeda ee xariiqda toosan.
- Laamta soo gasha, laamta soo noqota, iyo xariiqda toosan waxay ku yaalliin hal sagxad (flat surface).
- Laamta soo gasha, laamta soo noqota, iyo xariiqda toosan waxay ku yaalliin sagxado kala duwan.
4. Arday ayaa baaraya milicsiga iftiinka muraayad. Waxay yareeyaan xagasha soo-gaadhista (angle of incidence). Kee ayaa qeexaya waxa ku dhaca xagasha milicsiga (angle of reflection)?
- Waa korodhaa.
- Jawaabta saxda ah:Waa yaraadaa.
- Waa isku mid ahaanaysaa.
- Waa aan la saadaalin karin.
5. Maxay tahay sababta ay u yar tahay in cabbirka xagasha iftiinka ka soo baxa (angle of reflection) uu si sax ah u la mid noqdo xagasha iftiinka ku dhaca (angle of incidence)?
- Jawaabta saxda ah:Muraayadda laga yaabaa inaysan si sax ah ugu toosnayn khadka muraayadda ee jaantuska.
- Dusha muraayadda laga yaabaa inaysan simanayn.
- Khadka qalin ee fiiqan waa adag tahay in la arko marka la isticmaalayo protractor.
- Protractor-ku wuxuu ku cabbiraa ilaa heerka ugu dhow (degree).
- Iftiinka ka soo baxa laydhka (ray lamp) wuu ka ballaadhan yahay khadka qalin ee fiiqan.
