Question

Choose the correct properties of anode rays.

• A. The properties of anode rays depend upon the nature of gas taken in the discharge tube.
• B. Anode rays travel in a straight line.
• C. Anode rays consist of negatively charged particles.
• D. The mass of the particle is the same as the atomic mass of the gas inside the discharge tube.

Answer 1

Answer: (A), (B), (D)

The correct options are
A The properties of anode rays depend upon the nature of gas taken in the discharge tube.
B Anode rays travel in a straight line.
D The mass of the particle is the same as the atomic mass of the gas inside the discharge tube.

Properties of anode rays can be given as follows:
1. Anode rays travel in straight lines.
2. The e/m ratio of anode ray particles is different for different gases and is maximum for hydrogen.
3. Anode rays are deflected by electric and magnetic fields. Since they are deflected towards the negatively charged plate, they consist of positively charged particles.
4. The properties of anode rays depend upon the nature of gas taken in the discharge tube. Different gases give different types of positive rays, which contain particles having different masses and different charges.
5. The mass of the particle is the same as the atomic mass of the gas inside the discharge tube.
