| They travel from the cathode to the anode. | They travel from the anode to the cathode. |
| They cause a greenish-yellow fluorescence on a soda-glass screen. | They produce fluorescence on a zinc sulphide screen. |
| They are made of negatively charged particles. | They are made of positively charged particles. |
| They are affected by electric field i.e., they are inflected towards a positive field and deflected from the negative field. This shows they carry negative charge. | They are deflected by electric and magnetic fields but in a direction opposite to that of cathode rays. This means that these rays consist of positively charged particles called protons. |
| The ratio of charge (e) to the mass (m) remains same irrespective of the nature of the gas taken and of the metal forming the cathode. | The ratio of charge (e) to the mass (m), differs from gas to gas. |
