Goldstein gave an address to the chemical section on the influence of the kathode rays on the colour of metallic salts.
The changes so produced are more permanent than those produced by the kathode rays, though if the latter be allowed to act for a sufficiently long time there is less discrepancy in the results.
The therapeutic effects ofkathode and x-ray treatment are no doubt dependent in some degree on these changes, and it may be possible to discover which rays are hurtful, and to cut them off.
The second method is rather more complicated, and is based upon the fact that the kathode rays in a Crookes' tube can be deflected from their course by means of a magnet.
By a method somewhat similar to that used for determining the mass of kathode particles (see Sec.
This was experimentally verified by Kaufmann, who determined the velocities, and the ratios between the electrical charge and the inertia, of various kathode particles and similar particles which are emitted by compounds of radium (see Sec.
The tube is exhausted of air, and I am about to concentrate upon the gold an intense electric influence, which will have the effect of making it a kind of kathode pole.
You will recall that as long ago as the days of Crookes it was known that a kathode in an exhausted tube would project particles, or atoms, of its substance away in straight lines.
When a current is passed through an electrolyte, dissociation into ions takes place, the ions which are freed round the anode being called anions and those which are freed round the kathode being called kations.
The increased excitability at the kathode is katelectrotonus, and the lowered excitability at the anode anelectrotonus.
When a galvanic current is passed along a nerve its excitability is increased at the kathode and diminished at the anode.
In passing the current it must be remembered that the negative electrode or kathode is the more painful of the two, and its action more stimulating than the positive electrode or anode, which is sedative.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "kathode" in a variety of sentences. We hope that you will now be able to make sentences using this word.
