- 1Light: Is form of energy which enables us to see. Where there is no light, there is no life because all animals depend on plants and plants depend on light from the sun.Ilaysku waa nooc kamida tamarta kaasoo inoo ogolaada ineynu wax aragno.
meel aan ilays ka jirin, nololi kama jirto sababtoo ah nooluhu wuxuu ku tiirsan yahay dhirta, dhirtuna waxay ku tiirsan tahay ilahyska. - 2Light passes in straight line that is why the shadow forms. Light is considered the fastest thing in the world. The speed of light in vacuum or in the air is 30 000 000 m/silaysku wuxuu u safraa hab toos ah waxaana caddayn u ah samaysanka harka.
Ilayska waxaa lagu tilmaamaa sheyga ugu dheereeya adduunka oo dhan.
Xawaaraha ilaysku waxaa uu gaaraa in ku dhow 30 000 000 m/s. - 3Refraction of light is the bending of light rays when it passes through new medium. it consists: Incident ray: Refracted ray: Incident angle: Refracted angleIlays Jab waa marka falaarta ilayska ahi jabto marka ay meel meeshii hore ka duwan u gudubto.
Incident ray: Wa falarta so geleysa xadka
Refracted ray: Wa falarta ksi baxysa xadka
Incident angle: Xagal imaansho
Refracted angle: Xagal jab - 4Critical Angle: Is the angle which its refracted angle is 90. the critical angle is less than the total internal reflection.Critical Angle (Xagal riiqriiq): waa xagasha ilaysku ku qabo xagal 90 ah.
weyna ka yar tahay ilays noqod gudeedka. - 5Total internal reflection: Is the bouncing back of light internally to the more dense media. it is less than critical angle.
