Interference Phenomenon with Mobile Displays
Physics Education Volume 50, Number 4, ISSN 0031-9120
A simple experiment is presented in which the spacing and geometric pattern of pixels in mobile displays is measured. The technique is based on optical constructive interference. While the experiment is another opportunity to demonstrate wave interference from a grating-like structure, this can also be used to demonstrate concepts of solid state physics such as direct and reciprocal lattice vectors.
