Question

difference between cathode ray and alpha ray

Answer 1

in a cathode ray, the electrons are always released from a metal(since they conduct electricity). These electrons are actually the ones that are in the energy levels of metal atoms.But, the electrons in a beta ray are not the electrons in energy levels, but instead of that, are results of an nuclear process, where a neutron breaks into a proton and an electron. This is also a difference between cathode rays and beta rays.
