A question for you: if the cathode ray tube had never been invented, what would an oscilloscope look like? We’re not sure ourselves, but it seems like something similar to this mechanical tachyscope ...

Today’s oscilloscopes have far more functionality than their old cathode-ray tube (CRT) analog counterparts. At first glance, the proliferation of all of those knobs and buttons may seem overwhelming, ...
Oscilloscopes were once commonly called CROs, for the fact that they relied on cathode ray tubes for display. Since then, technology has moved quickly, and oscilloscopes these days almost entirely ...
In a cathode ray tube experiment, the CRT would be the area of interest and electrons are ejected from the cathode into the tube and are incident on the glass behind the anode. The statement that cathode is the electrode where reduction takes place is slightly misleading. This is because oxidation and reduction take place simultaneously (have to).
Cathode "rays" had been known for some time before Thomson. They were first observed as experiments in gas discharge tubes started to exploit better and better vacuums (the early experiments observed the varying forms of discharge in low pressure gases; cathode rays only become significant when there is very little gas left in the tubes).
electrons - How did J. J. Thomson prove that the cathode rays were made ...
