Professor Trowbridge's experiments with the cathode rays at the Jefferson Physical Laboratory have shown that the quality of glass constituting the Crookes tubes has very little to do with the ...

Scientists worked with electricity long before they understood that current was made of electrons. The cathode tube was a prime example. By switching on some voltage, scientists could make fluorescent ...

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 diffraction ...
