| A strong argument for the particle nature of cathode rays is that they |
| a) | Produce fluorescence | b) | Travel through vacuum |
| c) | Get deflected by electric and magnetic fields | d) | Cast shadow |
| (c)A charged particle is deflected by electric and magnetic fields. If the cathode rays is deflected by electric and magnetic fields then this is the strong argument for the particle nature of cathode rays. |
