A cathode ray tube is made of glass with a small amount of some kind of gas in it. It has metal electrodes at each end to pick up an electric current. The electrodes are named "positive” and "negative,” which were words used by Benjamin Franklin in the 1700s to describe electricity. A bright ray forms in the gas when an electric current is applied to metal electrodes. In the 1800s, an important scientist suspected that the negatively charged particles in a cathode ray were present in all atoms

Answer:

Make cathode-ray tubes with various materials and see whether the beam should be the same.

Explanation:

  • Cathode ray tube seems to be a transverse wave or vacuum tube throughout which the electron beam becomes transmitted onto a phosphor-coated panel to create a luminous position at that same point on a surface established either by influence on the electron beam of the varying magnetic field inside the container.
  • This beam flowing from either the negative (-) charge portion including its vacuum (cathode) to something like the positive (+) charges plate (anode).
