IEC PLANCK'S CONSTANT SIMPLE APPARATUS
A low cost instrument used to determine Planck’s Constant and discover that the wavelength of light determines the energy in the photons … not the amount of light.

The voltage that causes 2 microamps to flow through each selected LED is carefully measured. The wavelength of each LED is marked on the front panel. The wavelength must be converted to frequency and this can be plotted against the “breakover voltage” that causes the 2uA to flow. At this very low current, the LEDs are JUST at the point of conduction.

Requires a battery or power supply, digital voltmeter and micro-ammeter.

      ACSPH137 - Revolutions in modern physics - Quantum theory - A wide range of phenomena, including black body radiation and the photoelectric effect, are explained using the concept of light quanta
      ACSPH138 - Revolutions in modern physics - Quantum theory - Atoms of an element emit and absorb specific wavelengths of light that are unique to that element; this is the basis of spectral analysis
      ACSPH136 - Revolutions in modern physics - Quantum theory - On the atomic level, electromagnetic radiation is emitted or absorbed in discrete packets called photons; the energy of a photon is proportional to its frequency; and the constant of proportionality, Planck’s constant, can be determined experimentally (fo
