Question

The argument which favours the particulate nature of cathode rays is :

• A. they produce fluorescence
• B. they travel through vacuum
• C. they get deflected by electric and magnetic fields
• D. they cast shadows of objects present in their way

Answer 1

The correct option is C they get deflected by electric and magnetic fields

A strong argument for the particle nature of cathode rays is they are deflected by electric and magnetic fields. The deflection through electric and magnetic fields indicates that cathode rays are streams of minute particles carrying a negative charge.
