Cathode Ray facts

While investigating facts about Cathode Ray Tube and Cathode Ray Oscilloscope, I found out little known, but curios details like:

In 1887 he measured the heat generated by cathode rays and found that they were 1000 times lighter than the hydrogen atom and that their mass was the same as that of the atom from which they were generated.

how cathode ray tube works?

In April 1897 he discovered that cathode rays could be defected by a magnetic field and that their fluorescent path was the same regardless of the material or gas used.

What is cathode ray oscilloscope?

In my opinion, it is useful to put together a list of the most interesting details from trusted sources that I've come across answering what are the properties of cathode rays. Here are 14 of the best facts about Cathode Ray Experiment and Cathode Rays I managed to collect.

what cathode ray tube?

1. He designed instruments to pas cathode rays through a magnetic field and he was the first to determine the mass-to-charge ratio of cathode rays.

2. Strontium's dominant use is currently in the production of television cathode tubes, where it prevents the emission of X-rays.

3. He continued to experiment with the photographic plates and cathode ray tubes.

4. The German Physicist and Nobel Prize winner, Philipp Lenard, responsible for key discoveries involving cathode rays, joined the Nazi party in the 1920's and labeled Albert Eintsein's findings and studies as "Jewish physics"

5. A proto-video game known as the "cathode-ray tube amusement device." Created in 1947, it used a cathode ray tube connected to an oscilloscope to simulate an artillery shell shooting at objects.

6. This finding suggested that cathode rays were of the same form independent of their origin.

7. The Ferranti Mark 1 -- "the first commercially available general-purpose computer" -- "could store just over a kilobyte of data in cathode-ray tubes for high-speed access; a rotating magnetic drum offered 82 kilobytes of permanent storage."

8. X-rays were accidentally discovered by William Roentgen while experimenting with a cathode radiation .

9. Some televisions and computer monitors that use 'Cathode Ray Tubes' operate at upwards of 20,000-50,000 volts, which could literally send you flying across the room, if you were to get electrocuted by that area of the circuit.

10. A Nd magnet will deflect a beam of electrons in cathode ray tubes of a TV into really cool displays

Why cathode ray tube is evacuated?

You can easily fact check why cathode rays deflected in magnetic field by examining the linked well-known sources.

In 1948 the game Pong was designed to be played on a cathode ray tube (CRT) by Thomas T. Goldsmith Jr. and Estle Ray Mann.

The very first type of RAM was actually a CRT (Cathode Ray Tube) - source
