Product Details

Ready, Set, Glow! Clarify the difference between the intensity, or brightness, of light and the energy of light. In this teacher-developed kit, light is shined through a rainbow of filters onto a piece of phosphorescent material. The filters absorb some wavelengths of the light and transmit others. If the transmitted wavelengths of light are high enough in energy, the phosphorescent material will phosphoresce, or glow-in-the-dark! This demonstration allows students to explore the reasons for this brilliant phenomenon. A great kit to use when teaching absorption and emission of light, interpretation of transmittance graphs, and the photoelectric effect. Detailed Teacher Demonstration Notes included. All materials included are reusable. Concepts: Phosphorescence, transmittance, absorption, emission. Time Required: 15 minutes Materials Provided: Energy in Photons Demonstrator Card.
