Anode Cathode Discovery Rays

In summary, a perforated cathode is used in the discovery of anode rays because it allows for the passage of particles from the cathode to the anode, which was previously unknown. Anode rays are streams of positively charged particles that provided evidence for the existence of subatomic particles and helped in the development of atomic theory. The discovery of anode rays also contributed to our understanding of atomic structure by providing evidence for the existence of protons and paving the way for modern atomic models. Anode rays cannot be observed without a perforated cathode, as it creates a focused beam for observation and study. The discovery of anode rays had a significant impact on modern technology, leading to the development of technologies such as the cathode ray

Homework Statement: Why is perforated cathode used in the discovery of anode rays? Is there a hole in anode through which cathode rays pass and what causes the glow behind cathode and anode electrode? Is this glow due to the rays?

Relevant Equations: There are no equations.

I really tried to solve it a lot and the info that I gathered is :

Electrons or protons can be ABSORBED by cathode or anode so there must be some hole in the electrode for the rays to pass.
These electrons ionize the gas and those positive gas ions move towards cathode.

1. Why is a perforated cathode used in the discovery of anode rays?

A perforated cathode is used in the discovery of anode rays because it allows the anode rays to pass through and be observed. This is because the holes in the cathode act as a pathway for the anode rays to travel through, making it easier to detect and study them.

2. How does a perforated cathode help in the discovery of anode rays?

A perforated cathode helps in the discovery of anode rays by allowing them to pass through and be observed. Without the holes in the cathode, the anode rays would not be able to reach the other side and would not be able to be studied.

3. What is the purpose of using a perforated cathode in the discovery of anode rays?

The purpose of using a perforated cathode in the discovery of anode rays is to create a pathway for the anode rays to travel through. This makes it easier to observe and study them, leading to a better understanding of their properties and behavior.

4. How does a perforated cathode differ from a solid cathode in the discovery of anode rays?

A perforated cathode differs from a solid cathode in the discovery of anode rays in that it allows the anode rays to pass through, while a solid cathode does not. This makes it easier to study anode rays with a perforated cathode as they can be observed directly, whereas with a solid cathode, their presence can only be inferred.

5. What other experiments can be conducted using a perforated cathode in the study of anode rays?

Aside from the discovery of anode rays, a perforated cathode can also be used in other experiments to study the properties and behavior of anode rays. For example, the deflection of anode rays in electric and magnetic fields, as well as their interaction with different gases, can be studied using a perforated cathode.
