Description
Designed to determine the approximate value of Planck’s Constant using the elbow voltage in the characteristics curves of a number of LEDs. Modern LEDs (light emitting diodes) cover the range from deep blue (430nm) to infrared (950nm). By monitoring the voltage at which each LED just begins to emit light, a graph of energy input as a function of light emitted frequency can be plotted and an approximate value of Planck’s constant deduced. Complete with viewing tube but 5V power supply required to run apparatus (not supplied).
