  • Ukuphindwa kokukhanya

    Ukuphindwa kokukhanya

    Lapho ukukhanya kungena ngokugobile kwenye i-medium kusuka endaweni eyodwa, isiqondiso sokusakaza siyashintsha, ukuze ukukhanya kuphambuke lapho kuhlangana khona imidiya ehlukene.Izici: njengokuboniswa kokukhanya, ukuhlehliswa kokukhanya kwenzeka lapho kuhlangana khona imidiya emibili, kodwa ukukhanya okubonisiwe kubuyela kumsuka...
