Plancks Constant (Each) Magnetic Tiles & Boards Ideal for easy movement andLascells Plancks Constant 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. The system is an excellent illustration of modern electronics and gives a good investigation into a difficult topic in Post 16
