The rapid development of science and technology provides
new breakthrough in teaching methods of physics. One of them is with usage
the Physics Education Technology (PheT) software. In the event of the photoelectric effect,
where the surface of a metal (cathode) is illuminated with a beam of light (color
red, yellow, green, blue, and purple) with wavelengths (λ) such that
causing electrons to bounce out. The speed and energy of the radiated electrons
depends on the intensity and wavelength of the light source. Experimentally,
the voltage is slowed down continuously magnified until it should be zero. The voltage in question
this is called the stop potential (Vs). |
