Why do cathode rays produce sharp shadow of object placed in their path?
they are material particles!
Who identified cathode rays as subatomic particles?
Experiments with cathode rays led to the discovery of the electron.
Why did j.j reason the electrons must be a part of the atoms of all elements?
Cathode rays are negatively-charged particles.
What are cathode rays made from?
Cathode rays are a stream of electrons originating from cathode and moving to an anode, when high voltage electric potential is applied to the electrodes sealed in a glass tube containing gas at low pressure.Cathode rays are stream of negativley charged electrons getting detached right from neutral molecues due to high voltage and driven right from cathode to anode.
Which scientist discovered that cathode rays are made up of negatively charged particles?
English Physicist J.J. Thomson (1856-1940)
Why do cathode rays produce sharp shadow of object placed in their path?
they are material particles!
What is the charge of the particle in cathode rays?
Cathode rays are attracted to the positive charge on the anode! They are repelled by the negative charge on the cathode.
What is the evidence that show cathode rays consists of charged particles?
in a cathode ray tube the cathode rays move towards the anode(positively charged) fixed plate.
How do charged plates affect the plates of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
How do charged plates affect the path of cathode rays?
The electron particles in cathode rays have a negative charge. So if a plate is positively charged, it would attract the cathode rays, and if it was negatively charged, it would repel the rays.
Why are cathode rays deflected away from a negatively charged plate?
Alpha Rays are attracted to a negatively charged plate because they consist of positively charged particles.
Who identified cathode rays as subatomic particles?
Experiments with cathode rays led to the discovery of the electron.
What is the charge of the cathode tube particles?
Cathode rays are high speed electrons. So they are negatively charged.
In the cathode ray tube where do the particles originate?
In a cathode ray tube (CRT), the particles, which are electrons, originate at the heated cathode, becoming the so-called cathode rays. The electrons stream off the cathode and rush over to the anode.
What did Thomson conclude about the particles in cathode?
The immaterial nature and the aetherial hypothesis of cathode rays were proved wrong by J. J. Thomson. He concluded that the rays were comprised of particles. His entire works can be divided into three different experiments. In the first, the magnetic effect on cathode rays was studied while in the second, the rays were deflected by an electric field.
Who said Cathode rays are made up of negayively charged particles?
J.J.Thompson
What did Thomson conclude about the particles in cathode rays?
they are deflected toward positive terminal in an electric field
