Because -- they are?
Or, more specifically, because the particles within cathode rays act exactly like electrons. They either ARE electrons or they do a REAL good job of imitating them.
Cathode rays are electrons.
cathode rays can emit electrons anode can collect them
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.
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
momentum of the electrons
Cathode rays are electrons.
Cathode rays are electrons.
yes, cathode rays are streams of electrons
cathode rays can emit electrons anode can collect them
cathode rays is the beam of electrons.
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.
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.
they aren't. cathode rays are charged electrons, light is uncharged photons.
A modern day name for cathode rays is an electrons.

I dunno if I'm right but I think it is called electrons. I mean, electrons were in cathode Rays and were bent by a magnet right?
Thomson observed cathode rays with every element because cathode rays are composed of electrons, which are fundamental particles present in all atoms regardless of the element. When a high voltage is applied in a vacuum tube, electrons are emitted from the cathode and accelerate toward the anode, creating cathode rays. This universal presence of electrons in all elements allowed Thomson to consistently detect cathode rays across different materials. His experiments demonstrated that these rays were not dependent on the type of gas or metal used in the cathode.
