Overview of various methods for measuring a lens focal length
wp.optics.arizona.eduThis technique uses the Talbot effect: the image of a coherent wave with 2D periodic amplitude distribution, incident upon a diffraction grating, is regularly repeated. The distance between each self-image is the Talbot length ∆. If the wave interferes with another wave diffracted by a grating with a different spatial period, it creates a Moiré

2. Waves and the Wave Equation
www.brown.eduproperties of most wave phenomena, not only light waves. In many real-world situations, the velocity of a wave depends on its amplitude, so v = v(f). In this case, the solutions can be hard to determine. Fortunately, this is not the case for electromagnetic waves. 22 22 2 1 0 v ff xt water wave air wave earth wave
