X-rays


Which scientist discovered that cathode rays are made up of negatively charged particles?

J.J. Thomson discovered that cathode rays are made up of negatively charged particles. He conducted experiments using cathode ray tubes and found that the rays were deflected by electric and magnetic fields in a manner consistent with the presence of negatively charged particles.


Why anode rays also known as canal rays?

Anode rays are also known as canal rays because they were discovered to be positively charged particles produced in a cathode tube when the cathode rays strike a gas at low pressure. The particles travel in the opposite direction of cathode rays and move towards the anode or positive electrode, hence the name "anode rays."


How did JJ Thompson demonstrate the existence of the electron?

J. J. Thomson discovered the electron using an experiment involving cathode rays and a magnetic field. When subjected to the magnetic field, the cathode ray was deflected. If the magnetic field was flipped, the cathode ray was deflected in the opposite direction. This proved that a cathode ray was a stream of negatively charged particles that would later be deemed electrons.


Who discover anode rays?

Anode rays were discovered by German physicist Eugen Goldstein in 1886 while studying the behavior of cathode rays in a partially evacuated tube. They are positively charged particles that travel in the opposite direction of cathode rays when a high voltage is applied across the electrodes in the tube.

What was Thompson working with when he discovered the cathode rays?

Thomson discovered cathode rays when he was working with electrons. He was performing experiments with the electrons when one of them became electrically charged and a beam of light came from it, this creating a cathode ray.


What particles did Thompson discover and when did he discover them?

J.J. Thompson discovered the electron in 1897 through his experiments with cathode rays. He observed that cathode rays were negatively charged particles that were much smaller than atoms. This discovery led to the development of the plum pudding model of the atom.


Who discovered anode and cathode rays?

Cathode rays were discovered by JJ Thomson and carry a negative charge Anode rays were discovered by Goldstein and carry a positive charge.


What experiment did jj Thompson do?

What was discovered in the CRT?

Cathode rays (later revealed to be electrons).


What is Thompson's cathode ray?

homson conducted a series of experiments with cathode rays and cathode ray tubes leading him to the discovery of electrons and subatomic particles. Thomson used the cathode ray tube in three different experiments.


Who discovered canal rays?

Canal rays were discovered by Sir William Crookes in 1870. He observed these rays while studying the behavior of cathode rays in a vacuum tube.


Is it true that Electrons were discovered when an electric current was passed through gases at low pressures?

Yes, Sir J.J.Thompson did exactly that. ( although at that time the terms used for these phenomena were different). In 1897, Thompson heated a metal to produce cathode rays or electrons. These electrons were attracted towards an anode by providing a potential difference between the two electrodes. Between the cathode and electrode was air at very low pressure which did not stop these cathode rays. Sir Thompson studied these beams in the space between the anode and cathode.


Why positive rays called canal rays?

Positive rays are called canal rays because they are positively charged particles emitted by the anode and accelerated through a small canal or channel in the cathode of a cathode ray tube. These rays were discovered by Eugen Goldstein and were later studied by J.J. Thomson.


How was rayon x discovered?

X-rays were discovered accidentally by German physicist Wilhelm Conrad Roentgen in 1895 while experimenting with cathode rays in a vacuum tube. He noticed that a fluorescent screen in his lab started glowing even when it was covered to block the light from the cathode rays, leading to the discovery of X-rays.


What experimrents did jj Thomson?

After experiments with cathode rays Thomson discovered that these rays are deflected in an electrical field; and from this he proposed the existence of electrons.
