WebP-V and RMS are both calculated from the same data, such as an interferometer measurement, but the meanings are quite different. P-V Is the difference in height between the highest and lowest points on the surface. P-V is good at giving a “worst-case-scenario” for the surface. RMS is a method for describing the average deviation of the ... green coffee colombiaWebEach wavefronts is drawn at right angles to the wave direction.
