Difference between the cathode ray and beta ray
Illustrate the difference between the cathode ray and beta ray?
Expert
Actually normal on the wave front are termed as RAY, in the beta radiation there is wave packet and therefore no wave front. In cathode ray there is electromagnetic radiation and we can use word ray though in the case of beta particle we use the term beta radiation instead of betray.

No-hair conjecture (1960s): The conjecture (confirmed in the 1970s and 1980s) in general relativity that a black hole has merely three salient external characteristics: angular momentum, mass, and electric charge. All the other proper
