If we think. of a wave as having peaks and valleys with a zero-crossing between them, the phase of the wave is. defined as the distance between the first zero-crossing and the point in space defined as the origin.

Angle of repose

The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0° to 90°. The morphology of the material affects the angle of repose; smooth, rounded
