PLANCK'S CONSTANT APPARATUS

This compact apparatus has an integrated photocell, as well as a voltmeter and nano-ammeter, and is safe and simple to use. It is designed to determine Planck's constant and the work done in emitting an electron using the stopping potential method.

This Planck's Constant Apparatus features five light emitting diodes (LEDs) of known mean wavelengths, to act as light sources of differing frequencies. The intensity of the light emitted by them can be varied from 0 to 100%.

Planck's Constant Apparatus can be used in a variety of experiments, including demonstrating how electron energy is independent of light intensity and depends on wavelength.

ADVANTAGES OF THE PLANCK'S CONSTANT APPARATUS

  • Simple, safe and quick-to-operate - maximum convenience 
  • Compact device - does not take up too much space
  • Accuracy < 5%
  • Capable of demonstrating how electron energy is independent of light intensity 
  • Both 230 V, 50/60Hz and 115V, 50/60 Hz available 

EXPERIMENT TOPICS

Planck's Constant Apparatus is for use within the following experiment topics:

  • Energy of a photon
  • Mean emission wavelength for a light emitting diode
  • Photocell
  • Photo-electric effect and kinetic energy of electrons
  • How electron energy depends on wavelength 
  • How electron energy is independent of light intensity
