Natiijada casharka

Waxaan sharxi karaa sababta sawirada (muuqaallada) looga arko muraayadaha iyo sifooyinka sawirada muraayadaha.

Hordhac

Daraasadan, 'Milicsiga Muraayadaha', waxay kugu baraysaa sababta aad sawirkaaga uga aragto muraayadaha. Waa inaad hore u taqaan sidii iftiinka u socdo (iftoon) iyo in muraayaddu tahay dusha siman oo iftiinka ka soo booda.

Muuji qoraalka
Light reflects from mirrors obeying the laws of reflection. Some reflects into our eyes causing an image to be seen. The image in a mirror is located where the light rays seem to have come from. A reflection appears to be directly opposite the object, the same distance behind the mirror as the object is in front. The image in a mirror is the right way up but is laterally inverted.
