Question

In a discharge tube, anode rays originate when electrons collide with gas molecules.

• A. True
• B. False

Answer 1

The correct option is A True

1. Formation of anode rays: A cylindrical glass tube with two metal electrodes is taken and partially evacuated. And then a high voltage of current is applied at either end of the tube, which leads to a discharge of a ray from the negatively charged electrode (Cathode) going towards the positively charged electrode (anode).
2. The ray emitted is called a cathode ray. These cathode rays carry negatively charged particles (electrons).
3. When these electrons strike and ionize the gas sample in the glass tube, the electrons that are released from the gas reach the anode and produce anode rays (positively charged particles).
4. Hence, the given statement, ‘In a discharge tube, anode rays originate when electrons collide with gas molecules.’ is TRUE.
