  • It is a more useful instrument for research the rule of photoelectric effect:
  • Electrons inside an object will escape to the surface immediately when light irradiates on it.
  • Initial kinetic energy of the escaping electrons has nothing to do with intensity of light but increased along with increment of light frequency.
  • Saturation current is positively rated to intensity of light.
  • The instrument can also determine the stopping potential and qualitative analysis the Planck's constant (h=6.62619x l034 J.S).
  • Specification:
    • Color Filter: 700nm, 635nm, 500nm, 460nm, black plate.
