"WebBut a ray vector will always be normal to the wavefront and pointed in the same direction that the wavefront is traveling at that location. How do you find the direction of a wave front? The wave fronts are oriented along y, i.e. the wave runs along the x axis, therefore, in the direction of the wave vector k. " - How is wavefront different from a ray
