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 Plancks constant deduced. The system is an excellent illustration of modern electronics and gives a good investigation into a difficult topic in Post 16 physics. The LEDs are mounted in a self
