English: Performed by Prof. Oliver Zajkov at the Physics Institute at the Ss. Cyril and Methodius University of Skopje, Macedonia.
Français : Démonstration de l'effet photoélectrique sur la charge électrique d'un corps.
Un électroscope est d'abord chargé négativement. Une lampe est approchée d'une plaque métallique fixée à l'appareil. L'effet photoélectrique arrache des électrons à la plaque et l'électroscope redevient électriquement neutre. Une plaque de verre placée entre la source lumineuse et la plaque métallique annule l'effet, alors que l'électroscope chargé positivement demeure chargé malgré la lampe. Expérience réalisée et expliquée par le professeur Oliver Zajkov de l'Institut de physique de l'université Saints-Cyrille-et-Méthode de Skopje de Macédoine. Македонски: Изведен од проф. Оливер Зајков на Институтот за физика на Природно-математичкиот факултет во Скопје. |
