TN - Investigating Planck's Constant with LEDs

Workshop Abstract: Planck’s constant is a fundamental constant of nature that is the most basic quantity in quantum physics and, potentially, in all of physics. It sets the scale of the quantum world and is deeply connected to our description of every single subatomic particle in the universe. This workshop will introduce a simple laboratory activity that brings quantum physics to life by allowing your students to determine Planck’s constant for themselves. The circuit only involves LEDs of different colours, playdough, a 6 or 9 V battery and a multimeter. This workshop is based on the classroom resource Investigating Planck's Constant with LEDs.
