What is "Chaff" - Definition & Explanation

A component in cotton of trash (q.v.) in the form of a heterogeneous assortment of vegetable fragments, most of them being small pieces of leaf, leaf bract (a small form of leaf growing beneath the boll) and stalk. "Broken fragments of twig and small branches, particularly when brittle, may be broken up further in ginning and are then also regarded as "chaff". Another component of chaff is the silvery lining of the boll interior, sometimes termed "shale", particularly the partitions dividing the locules before the boll opens."
Lightweight reflecting material, typically consisting of aluminum foil strips or metal-coated fibers, that is released in the atmosphere to produce radar echoes. Initially developed as a military countermeasure, chaff is used in meteorological research to enable tracking of air motions in conditions with no natural airborne scatterers or to provide stronger echoes than those from natural scatterers.
