What did J. J. Thomson observe when he applied electric voltage to a cathode ray tube in his famous experiment?
The stream of cathode ray particles was moving very slowly.
The glass opposite of the negative electrode started to glow.
The electric voltage had little effect on the stream of particles.
The tube contained two pieces of metal that served as electrodes.

The glass opposite of the negative electrode started to glow.
(Thomson observed a fluorescent glow on the glass where the cathode rays hit; this, along with later deflection experiments, led him to identify the rays as streams of negatively charged particles — electrons.)
