caption: Interference of two circular waves – Wavelength (decreasing bottom to top) and Wave centers distance (increasing to the right). Absolute value snapshots of the (real-valued, scalar) wave field. As time progresses, the wave fronts would move outwards from the two centers, but the dark regions (destructive interference) stay fixed.
caption: Colors seen in a spider web are partially due to diffraction, according to some analyses. [4]
caption: In a prism, material dispersion (a wavelength -dependent refractive index ) causes different colors to refract at different angles, splitting white light into a rainbow .
