The Phantastic Photon

A CIPT Lab Exercise in Modern Physics

Abstract

The color of light is directly related to the energy and wavelength of the photons that compose that light. Students investigate these relationships by shining colored light from super-bright LEDs onto glow-in-the-dark tape and fluorescent paints. First they determine which LEDs activate the tape, measure their wavelength and calculate photon energies. Then students are asked to apply their knowledge of photons to predict which paints will fluoresce when exposed to light from a particular LED.
