About
Uses time - lapse photography to show how water moves into and through unsaturated soil. Points out how strata, such as hard pans or coarse sand layers, slow down the advance of a wetting front and how saturated and unsaturated flow differ. Dye tracks illustrate how soluble fertilizers move in irrigation furrows.
Describes the characteristics of propagated radio waves of various frequencies, ground and sky waves, the effects of the ionsphere on sky waves, and the effects of favorable and unfavorable atmospheric conditions.
