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

Answer

Answer:

The glass opposite of the negative electrode started to glow.

Brief Explanations:

In J. J. Thomson's cathode - ray tube experiment, when an electric voltage was applied, the cathode - ray particles (electrons) were attracted to the positive electrode, and the glass opposite the negative electrode (cathode) started to glow due to the interaction with the cathode rays. The other options do not describe the observed phenomenon.
