Example Sentences

Because as each wave front moves from air to water, it slows down.

The student will note that for the sake of greater precision we here say wave front instead of wave.

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.

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.
