勒納德效應

水滴飛散時，會產生負離子，細微的水滴帶正電，周圍的空氣便會帶負電，發現此現象的是獲得諾貝爾物理獎的德國物理學家勒納德，於是以發現者命名，將其稱為勒納德現象。

簡介

Lenard(1915)found that when water isatomized(e.g. on impact of a waterdroplet), negative and positive charges are SEPARATED.

歷史

Molecules which are torn from the surface of the water bear aNEGATIVEcharge(small negative ions) whereas large drops of the entire mass ofwaterare POSITIVE.
This provided an unexpected explanation forthe refreshing,invigorating effect of residences does to a waterfall or spring, or even after rain.
