Abstract
Luminous bacteria suspended in sea water in a glass test tube, touching the oil surrounding a quartz plate, made to vibrate by a high frequency (400,000 cycles), high voltage (50,000) electric field, are broken up and eventually (about 1 hr.) destroyed by the sound waves that pass through the oil, glass and sea water. Heating of the sea water was prevented by a coil of circulating ice water and controls were carried out to show that the high frequency electric field was not producing the effect.
