Diffraction Materials Card
PRODUCT DETAILS
Is it a wave or a particle? Use this handy card containing five 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 laboratory setting, measurements of the diffraction pattern can be used to calculate the wavelength of laser light used. Or knowing the wavelength of the laser, calculate the line spacing of the grating. A must-have for any discussion of wave optics. Grades 5-12.
