Which of the following statements is not true about canal rays?
Which of the following statements is not true about canal rays?
- A. They travel in straight line.
- B. They are made up of positively charged particles.
- C. Their e/m ratio is same for all gases.
- D. These rays produce fluorescence on \( Z n S \) screen.
Step-by-step solution
Canal rays (anode rays) consist of positively charged particles whose e/m ratio depends on the gas used in the discharge tube because different gases produce different ions. Hence, the e/m ratio varies with the gas, making statement C false. Statements A, B, and D are true properties of canal rays.
