Faahfaahinta casharka

Natiijada casharka

Waxaan sharxi karaa midabka shay marka uu ku jiro iftiin cad iyo marka uu ku jiro iftiin midab leh.

Hordhac

Salaan dhagaystayaashayda qaaliga ah! Kahor intaadan daawan casharkan, waxaad hore uga yaqaan tahay sida iftiinka u socdo iyo sida uu uga milicsado dusha sare. Casharkani wuxuu ku saabsan yahay sababta walxaha ugu ekaadaan midabyo kala duwan marka ay ku jiraan iftiin cad iyo marka ay ku jiraan iftiin midab leh. Waxaadna baran doontaa sida loo sharxo midabka shayga iyadoo la tixgelinayo nooca iftiinka ku dhacaya.

Muuji qoraalka
Colour is detected in the eye by the R, G and B ‘cone cells’ that each detect a range of colours of light. The colour of an object in white or coloured light depends on the amounts of R, G and B light it is reflecting. White objects reflect all colours of light so look the same colour as the incident light (whether white or coloured). The colours of light that an object does not reflect are absorbed. Black objects absorb all colours of light. In red/green/blue light, an object will appear red/green/blue if it reflects that colour, and black if it does not.
