Material Detail

[en] The simulation allows one to explore the photoelectric effect, i.e. the emission of electrons by an illuminated metallic surface (called an electrode) much in the same way as in a real laboratory. The user can change the intensity of the illuminating beam, select different wavelengths by rotating a diffraction grating, adjust the voltage of the illuminated surface (relative to a similar surface located nearby) and repeat the experiment with electrodes made of various metals. _________ [fr] La simulation permet d'explorer l'effet photoélectrique, c'est-à-dire l'émission d'électrons par une surface métallique exposée à un faisceau lumineux. D'un manière analogue à ce qu'on peut faire dans une véritable laboratoire, l'utilisateur peut varier l'intensité lumineuse incidente sur la surface, choisir la longueur d'onde de la lumière en ajustant un réseau de diffraction, modifier la tension entre la surface illuminée et une seconde surface simulaire, et répéter l'expérience avec différents métaux.
