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 is the difference between electron beam and cathod rays?
X ray is light and belongs to the family of electromagnetic waves. It is said to be photon whose rest mass is zero. X ray does not have charge.Electron is considered as particle which has mass, of 9.1 x10 -31 kg.Electrons posses negative charge that equals 1.602 x 10 -19 C
What are the uses of Cathode Rays and Anode Rays?
cathode rays can emit electrons anode can collect them
In cathode ray tube cathode and anode rays travel opposite to each other but they are not neutralized. why?
There is no such thing as anode rays. The cathode rays (aka electron beam) just travels from cathode to anode.
What are the rays in the cathode ray tubepositive or negative or neutral?
The rays produced in a cathode tube in early experiments were actually just streams of electrons. They had a negative charge, which was discovered by JJ Thomson when he placed a magnet next to his cathode ray tube and say the ray bend.
Is cathode rays are material particles?
Cathode rays are streams of electrons that travel from the negatively charged cathode to the positively charged anode in a cathode ray tube. They are not material particles in the traditional sense because they do not have mass or volume, but rather behave as electron beams.
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.
Why cathode rays are negatively charged?
Cathode rays are negatively charged because they are composed of electrons, which have a negative charge. When a high voltage is applied to the cathode in a vacuum tube, electrons are emitted from the cathode and accelerated towards the anode, creating a beam of negatively charged particles known as cathode rays.
What did J J. Thomsons experiment show?
Thomson set out to prove that the cathode rays produced from the cathode were actually a stream of negatively charged particles called electrons.

Cathode rays were found to be made of protons.?
Cathode rays are electrons.
What are the uses of Cathode Rays and Anode Rays?
cathode rays can emit electrons anode can collect them
Why cathode ray are not electro-magnetic waves?
A cathode ray is a stream of electrons, not a stream of photons like the electromagnetic wave. It's a different type of particle. The electrons don't move at light speed in a vacuum; also, they are electrically charged.
What is the modern day name for cathode rays?
Cathode rays are electron beams.
How did William Crookes determine the nature of the beam in cathode ray tube?
In his investigations of the conduction of electricity in low pressure gases, William Crookes discovered that as the pressure was lowered, the negative electrode (cathode) appeared to emit rays (the so-called cathode rays, now known to be a stream of free electrons, and used in cathode ray display devices).
What is modern name for cathode rays?
A modern day name for cathode rays is an electrons.
