Diffraction Materials Card, Pack of 25

Is it a wave or is it a particle? Use this handy card containing 5 different materials to investigate the effects of diffraction, and explore the fundamental questions of quantum mechanics! This card can be used as a demonstration aid to discuss the qualitative nature of diffraction or it can provide an easy introduction to a more quantitative analysis using Young's equations for diffraction. Quickly and easily demonstrate the relationships between line width, wavelength, and diffraction angle. In a labora
