2. The nature of these rays depends on the gas used in the discharge tube.
3. These rays travel in straight lines. They cast a shadow of the object in their path.
4. These rays get deflected by an electrical field, and bend towards the negative plate. Thus the deflection of the positive rays is in a direction opposite to that shown by the cathode rays.
5. These rays are also deflected by the magnetic fields in the direction opposite to that of the cathode rays.
6. These rays can produce mechanical as well as chemical effects.
7. The ratio of charge (e) to mass (m), i.e.,(e/m) for the particles in the positive rays is not the same for all gases.
8. The ratio e / m for the positive rays is very low as compared to the e / m value for cathode rays.
9. Positive rays affect photographic plate.
10. They can produce ionization in gases.
11. They cause fluorescence.
