Was it a wave of some kind? A particle? The eminent Cambridge physicist J.J. Thomson solved the puzzle in 1897: The cathode-rays inside the tube were comprised of negatively charged particles ...

Professor Trowbridge's experiments with the cathode rays at the Jefferson Physical ... such as one obtains by the use of the Thomson or Tesla coil and by the use of only one terminal.

A DIFFRACTION pattern was obtained by passing a cathode ray beam through a thin sheet of mica, with an apparatus similar to that used by G. P. Thomson in his interesting experiment on the ...
