Abstract. This article discusses two methods that will determine Planck’s constant using a Vernier LabQuest Interface, Power amplifier, and light emitting diodes (LEDs). While some mathematical manipulation is necessary, the calculations are workable, and the values produced are close to the accepted value. These procedures are easily convertible to student experiments.
