Planck's Constant By LED
Product Code : JA-PLE-4280
The Planck's Constant By LED apparatus (SKU JA-PLE-4280) is listed for determining Planck's constant from light-emitting diodes of different colours, a standard modern physics practical. The voltage at which each LED just begins to emit light is related to the energy of the photons it produces, so plotting that voltage against frequency gives Planck's constant. This Planck's constant by LED apparatus suits class 12, B.Sc and engineering physics laboratories.

Applications of the Planck's constant by LED apparatus
For each LED the threshold voltage V is measured and the emitted wavelength is known, so eV is set equal to the photon energy hc divided by wavelength and Planck's constant h is found from the slope of V against frequency.
