Doubt Experimental Rays Set

In summary, the doubt in the experimental setup for canal rays concerned the location of the luminous stream of particles, specifically whether it was to the right or left of the cathode. After receiving helpful links from another member, it was determined that the stream was observed to the right of the cathode.

Thanks for the reply Spinnor. I got it now from your links. They are very useful

1. What is the purpose of the canal rays experimental setup?

The purpose of the canal rays experimental setup is to study the properties of positively charged particles, known as canal rays, produced in a cathode ray tube.

2. How does the canal rays experimental setup work?

The setup consists of a cathode ray tube, a perforated cathode, and an anode. The cathode ray tube is filled with a gas at low pressure and a high voltage is applied between the cathode and anode. This causes the cathode to emit a beam of electrons, which collide with gas molecules. Some of these collisions produce positively charged particles, or canal rays, which are then attracted to the anode and pass through the perforated cathode.

3. What are the components of the canal rays experimental setup?

The main components of the setup are a cathode ray tube, a perforated cathode, and an anode. Additional components may include a power supply, a vacuum pump to maintain low pressure in the tube, and a measuring device to detect and measure the properties of the canal rays.

4. What can we learn from the results of the canal rays experimental setup?

The results of the experiment can provide insights into the nature of positively charged particles, such as their charge-to-mass ratio and their ability to be deflected by electric and magnetic fields. These findings can also be used to further our understanding of atomic structure and the nature of matter.

5. Are there any limitations to the canal rays experimental setup?

One limitation of the setup is that it can only detect positively charged particles, so it cannot be used to study neutral or negatively charged particles. Additionally, the results may be affected by external factors such as temperature and pressure, so careful control of these variables is necessary for accurate results.
