The coherent sources must be very close to each other. the central bright remains white and all the other colours will form individual maximas with the least wavelength violet forming its bright close to the central … 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.
