How are cathode rays originated?

its negatively charged particles of matter,Thomson knew that opposites attract but these the positive charged anode,so he reasoned that the paticles must be negatively charged! : )! Wooooo! Go J.J Thomson


What hapens at the caTHODE?

At the cathode, a reduction reaction occurs during electrochemical processes, such as in batteries or electrolytic cells. Electrons flow into the cathode from an external circuit, causing the reduction of cations (positively charged ions) that migrate towards it. This process often results in the deposition of material, such as metal ions gaining electrons to form solid metal. In summary, the cathode is where reduction takes place, facilitated by incoming electrons.


What is a device which receives electrical impulses and restores them to a visual form with a modified cathode ray tube?

That would be a CRT Monitor (CRT stands for Cathode Ray Tube), or the big clunky monitor that you had such a hard time getting rid of when you got your LCD


What are the Adavantages and disadvantages of vacuum tube?

when the vacuum sucks up things it goes through the tube and into the bag ...Unless you are talking about electronics, then a vacuum tube is used to form an amplifying circuit. Some tubes can emit cathode rays onto a screen (Cathode Ray Tube = CRT) to display a picture and some can function as diodes to regulate current flow.


What did the phydicist roentgen discover about a cathode-ray beam striking a glass surface?

Physicist Wilhelm Conrad Roentgen discovered that when a cathode-ray beam strikes a glass surface, it produces a new form of radiation that he termed X-rays. This radiation could penetrate various materials, including human tissue, and was capable of producing images of the internal structures of objects, such as bones. His groundbreaking discovery in 1895 laid the foundation for medical imaging and numerous applications in science and technology.

Do metals form at the anode or cathode?

Metals typically form at the cathode during electrolysis. This is because positively charged metal ions are attracted to the negatively charged cathode where they gain electrons and deposit as solid metal.


How scientist try to answer questions that cannot be tested with experiments?

To answer a specific question, scientist form a hypothesis. If the hypothesis cannot be testable or answered, they'll give you a prediction of what will most likely happen from the results of the hypothesis.

What happens is Scientists conduct experiments and if all the Scientists who conducted the same experiment come up with the same results, the call it a LAW.


How do you know the students in the above study are acting as scientist?

Students could be seen to be acting as scientist if they are following the scientific method - Make observations, postulate a hypothesis, and form and complete experiments or further observations to confirm or refute that hypothesis.


How do cathode rays form?

Cathode rays are the emission of free electrons form the negative pole of an electric circuit. To get this to happen you need to warm the cathode and place it in a vacuum tube with a high voltage across it. The electron then jump form the cathode and fly across the empty tube to the anode (positive end). They may be bent by magnetic fields in flight.
