Which scientist did experiments involing a form of cathode ray tube?
J.J. Thomson used cathode ray tubes to prove the existence of electrons.
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.
When figuring out an answer to a question, scientists use the scientific method. the scientific method is a series of steps that start like this: Ask a question Do some background reaserch on this question Form a hypothesis, what the scientist thinks the answer might be Do some experiments to collect data on the question, it can turn out either way, in favor of the hypothesis or not in favor of it. Then they analyze…
All metals contain electrons in the form of free electrons. If we apply a suitable electric potential to a metal, these electrons can be ejected from the surface of the metal. Cathode rays came from the negatively charged electrode called cathode, inside a cathode ray discharge tube, the experiment was done by J.J. Thomson. The stream of negatively charged particles called electrons that went from the metallic cathode to anode(positively charged) plate was called the…
Explain how scientists try to answer questions that cannot be tested with experiments and give an example?
There is no full form. They were discovered by accident by a scientist named Wilhelm Röntgen in 1895 while using Cathode ray tubes. As he nor anyone else knew what they were or what they were made of at the time, they were called X-rays. In science and math, X refers to an unknown. They were also called "Röntgen rays" for a while.
