Which statement(s) is(are) true for photomultiplier tubes? I     Photomultiplier tubes are very sensitive detectors, amplifying the photoelectron current by approximately 1 million. II     Emitted photoelectrons are accelerated toward positively charged electrodes called dynodes. III     Electrons strike the dynode with a kinetic energy less than the original emitted kinetic energy. IV     For each electron striking a dynode, more than one electron is knocked free. The additional electrons are accelerated toward the next dynode in the detector where amplification is repeated. Select one: a. II, III, and IV b. II c. I, II, and IV d. II and III e. I and IV
