What is the charge of the particle in cathode rays?
Cathode rays are attracted to the positive charge on the anode! They are repelled by the negative charge on the cathode.
How positive rays are produced in a discharge tube?
deflected away from a negative plat
Who discovered anode and cathode rays?
Cathode rays were discovered by JJ Thomson and carry a negative charge Anode rays were discovered by Goldstein and carry a positive charge.
What did Ernest Rutherford discover about the structure of an atom?
Rutherford discovered the atomic nucleus and the proton. Rutherford don't discovered the atom. A short answer for the Rutherford atomic model: the atom is composed from a central part - a nucleus, positively charged, surrounded by electrons - very small negative charged particles.
X-rays are not deflected by magnetic fieldWhat does this indicate about yhe nature of rays?
That they have neither a negative or positive charge
Why do cathode rays move from the negative end of the tube to the positive end?
Because an electron carries a negative charge and in electricity, opposites attract. Particles with a negative charge will be drawn to the positive charge in the cathode tube.
Are anode rays emitted from anode?
There are no rays assign as anode rays (cathode rays are there in a discharge tube) but during discharge tube experiment positive rays are observed which are generated by decomposition of gaseous molecules present in the tube. X-rays are produced by striking of cathode rays with anode so x-rays may be called as anode rays.
Are cathode rays deflected toward a negatively charged plate in an electric field?
Yes. Cathode rays, otherwise known as electrons, are repelled by a negative charge, and attracted to a positive charge.
Why Rutherford had not used gamma rays instead of alpha rays inh his experiments?
Gamma ray is neutral. More over it is an electromagnetic radiation having high penetration power. So scattering by the gold nuclei is not at all possible ===================================== How about the fact that alpha rays are easy to produce, control, measure, and protect against, whereas Rutherford had no convenient source of gamma rays, no way to control them where he did find them, and was not much interested in exposing himself to a shower of radiation more energetic than X-rays, even in the interest of science.
What effects the ozone have on the humans?
The ozone has both positive and negative effects. It protects us from UV rays but also acts as pollutant.
Who discovered beta rays?
Ernst Rutherford discovered beta decay. Henri Becquerel discovered that there were emissions somewhat like X-rays originating from uranium. Ernst Rutherford discovered that two different kinds of emissions were coming from the uranium, and he named these alpha and beta. He published a paper on this in 1897.
When did Paul Villard discover gamma rays?
Paul Villard discovered gamma rays in 1900, after recognising them as different to X-rays as they had a much greater penetrating power. Gamma rays were not thought of as part of the electromagnetic spectrum until 1914 when Rutherford showed that they were a form of light.
