This video explains an A Level Physics Practical: finding the value of Planck's constant with LEDs.
How to conduct an experiment to find the value of Planck's constant using an LED, a voltmeter and a variable power supply. Planck's constant, h, is the constant of proportionality between the particle-like properties and the frequency of the associated wave.
