Electrons can be "seen" in e.g. particle colliders by the way the interact with media they pass through ... WebHow cathode rays are formed? Cathode rays come out from the cathode as the cathode is charged negatively. So, these rays strike and ionize the gas sample present inside the container. The electrons which are ejected from gas ionization travel towards the anode. These rays are electrons which are produced from the gas ionization inside the tube.
