Question

The nature of anode rays depends upon:

• A. nature of gas filled in the discharge tube
• B. nature of electrode
• C. nature of metal
• D. none of these

Answer 1

The correct option is A nature of gas filled in the discharge tube

The nature of the anode rays depends upon the gas taken in the discharge tube. Different gases give different types of positive rays, which contain particles having different masses and different charges.

Therefore, the (e/m) ratio is not constant for positive ray particles obtained from different gases.
