J. J. Thomson presented the results of his experiment with cathode-ray tubes (Figure P2.106) in which he proposed that the rays were actually beams of negatively charged particles, which he called "corpuscles." a. What is the name we use for these particles today? b. Why did the beam deflect when passed between electrically charged plates, as shown in Figure P2.106? c. If the polarity of the plates were switched, how would the position of the light spot on the phosphorescent screen change? d. If the voltage on the plates were reduced by half, how would the position of the light spot change?
