Examples from the Web for wave front

Historical Examples

  • With a dense prism, the wave-front of the shorter waves is more tilted towards the base than the wave-front of the longer waves.

    The Mechanism of Life

    Stphane Leduc

  • Hence the wave-front is flattened, the curvature of the refracted wave being less than that of the original wave of diffusion.

  • Hence the wave-front is tilted towards the base of the prism, and this tilting is repeated when the wave-front leaves the prism.

  • The middle of the wave-front now travels faster than the flanks, and the curvature is increased.

  • The contrary is the case when the wave-front passes into a medium where its velocity is greater.


wave front in Science

wave front

  1. The set of points in space reached by a wave or vibration at the same instant as the wave travels through a medium. Wave fronts generally form a continuous line or surface. The lines formed by crests of ripples on a pond, for example, correspond to curved wave fronts.
