Question

Which of the following statements (is/are) incorrect regarding anode rays?

• A. Anode rays consist of fast moving electrons
• B. Anode rays are produced by the ejection of electrons from the anode material
• C. Both $A$ and $B$
• D. None of these

Answer 1

The correct option is C Both $A$ and $B$

Anode rays are formed in a gas-discharge anode ray tube is as follows.

These collide with atoms of the gas, knocking electrons of them and creating more positive ions.

These ions and electrons, strike more atoms, creating more positive ions in a chain reaction. So they are not produced by ejecting of electrons.

This process is followed when hydrogen gas present in the tube from which electron knocks out and rest protons are called anode ray.

So, option $C$ is correct.
