Question

How do cathode rays differ from anode rays ?

Answer 1

Cathode rays:

1. They have negatively charged ions called electrons.

2. Cathode rays deflect towards the positive plate of an electric field.

3. The charge to mass ratio (e / m) for the gaseous particles taken in the discharge tube.





Anode rays:

1. They have positively charges material particles.

2. Anode rays deflect towards the negative plate of an electric field.

3. The charge to mass (e / m) ratio of the particles in anode rays depends upon the nature of the gas taken in the discharge tube

Cathode rays	Anode rays
These rays travels from the cathode to anode	These rays travel from the anode to cathode
They are made of negatively charged particles	They are made of positively charged particles
They produce a greenish yellow flourescence on a soda glass screen	They produce flouresence on a zinc sulphide screen
They are affected by an electric field i.e, they are inflected towards a positive field and deflected owards a negative field	They are deflected by electric field but in a direction opposite to that of cathode rays
