Description
✅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 so called 'red limit frequency'.
✅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
✅Anode Current of X-rays Tube: ¡Ü2mA
✅Sensitive Component: vacuum phototube
✅Light Source: 12V/20W incandescent lamp
