41. Rainbows are the result of a combination of internal reflection and dispersive refraction of light in raindrops. 42. In surface science, the term " adhesion " almost always refers to dispersive adhesion. 43. Simple smooth polymer surfaces without any microstructures are commonly used for these dispersive adhesive properties. 44. Laboratory tests used to disagnose a soil as dispersive focus on the H + in acidic soils. 45. On the other hand, oceanic flows are dispersive but essentially non rotational and therefore are not turbulent. 46. EDS is often contrasted with its spectroscopic counterpart, WDS ( wavelength dispersive X-ray spectroscopy ). 47. It is possible to use prisms rather than gratings as a dispersive elements, as in Figure 3. 48. This dispersive electrode is frequently and mistakenly called a " ground pad " or " neutral electrode ". 49. The Dorris and Gray . or Schultz methods can then be used to calculate the dispersive surface energy. 50. So the theory of dispersive body waves has most applications in the theory of seismic inverse Q filtering.
