Viscoelasticity: The property of materials to both resist flow when a
stress is applied and rapidly return to their original state once the
stress is removed.
Wavefunction: The wavefunction of a system is a mathematical function
that describes the particles in a system (e.g., electrons) as a wave.
The square of the wavefunction is the probability density of a
particle’s location in space and time.
Waveguide: An object composed of multiple layers of materials with
different refractive indices that confines and directs waves by
means of total reflection of the wave within itself.
Wenzel wetting: A wetting state in which water rests on a surface whose
morphology has been altered so that in a given area, water is in
contact with more surface than if the surface were completely flat.
