Question

what do Canal rays consist of? class9 science​

Answer 1

Answer:

Anode ray tube

These rays are beams of particles moving in a direction opposite to the "cathode rays", which are streams of electrons which move toward the anode. Goldstein called these positive rays Kanalstrahlen, "channel rays" or "canal rays", because they were produced by the holes or channels in the cathode.

Answer 2

Explanation:

Unlike cathode rays, canal rays depend upon the nature of gas present in the tube. It is because the canal rays are composed of positive ionized ions formed by ionization of gas present in the tube. The charge to mass ratio for the particles of ray was found to be different for different gases. An anode ray (also positive ray or canal ray) is a beam of positive ions that is created by certain types of gas-discharge tubes. They were first observed in Crookes tubes during experiments by the German scientist Eugen Goldstein, in 1886.Later work on anode rays by Wilhelm Wien and J. J. Thomson led to the development of mass spectrometry.
