Determination of the Planck Constant through the use of LEDs
Planck’s constant plays a fundamental role in the quantum mechanics theory. The numerical value of this constant can be experimentally obtained by means of the study of a wide variety of physical phenomena. The main goal of the present laboratory exercise is the determination of the numerical value of the Planck constant using LEDs by means of two different theoretical models and an Arduino automatized measurement. To achieve this, four different LEDs spectra were provided and their current-voltage curves were measured. Results from the two proposed methodologies are compared and discussed.
