Cylindrical wavefront
Web2. Cylindrical wavefront. When the source of light is linear in shape, such as a fine rectangular slit, the 9.3 wavefront is cylindrical in shape. This is because the locus of all such points which are equidistant from the linear source will be a cylinder [Fig. 9.1(b)] of 3. Plane wavefront.
