Can a Vibrating, Charged Block in Deep Space Produce Radio Waves?

In summary, a linear accelerator was used to irradiate plastic blocks in the 1960s, causing a static charge to accumulate. Striking the blocks caused a tree-shaped discharge path through the plastic, as shown in attached photos. The question is raised about the potential for producing and receiving radio waves if the charged block were placed in deep space and mechanically vibrated. The answer is yes for both, but if the receiving antenna is also vibrated and synced to compensate for propagation delay, reception would not cease.

My questions follow this short preface re: attached photos.

Sometime ago in the mid 1960's, a friend had access to a linear accelerator. In the very late evening, we irradiated several plastic blocks of the dimensions ~10x10x2 cm. Individually, the plastic blocks were in a10 MeV electron beam (intensity forgotten) for about 20 minutes. Afterwards, using a grounded Phillips screwdriver and small hammer, the blocks were struck on the edge such that the accumulated static charge was violently discharged to ground. The tree-shaped discharge path through the plastic is evident in the first photo. The second edge-on photo shows the discharge exit point and that the “tree” is confined to the interior of the plastic block but is three-dimensional.

I “found” the block in my old roll-top desk and something caused me wonder what would be the consequence of placing the charged plastic block in deep space and mechanically vibrating it.

- Would the block produce radio waves?
- Would a suitable antenna receive the waves?
- If the receiving antenna were vibrated in same manner and synchronized to compensate for propagation delay, would reception cease?

Thanks for your replies.

I find your experiment with the charged plastic blocks in the linear accelerator very interesting. It is not uncommon for charged particles to accumulate on surfaces when exposed to high energy particle beams, and the tree-shaped discharge pattern in the photos is a common phenomenon.

Regarding your questions about placing the charged block in deep space and mechanically vibrating it, there are a few factors that need to be considered. First, the block would need to be in a vacuum in order to maintain its charge, as any particles in the surrounding environment would neutralize the charge. Second, the block would need to be vibrating at a high frequency in order to produce radio waves, as the frequency of the waves is directly related to the frequency of the vibrating object.

In theory, the vibrating charged block could produce radio waves, but it would depend on the frequency and strength of the vibrations. A suitable antenna could potentially receive these waves, but it would also depend on the sensitivity and frequency range of the antenna.

If the receiving antenna were also vibrating in the same manner and synchronized to compensate for propagation delay, it is possible that reception may cease. However, this would also depend on the distance between the two objects and any potential interference from other sources. Further experimentation and analysis would be needed to determine the exact effects of vibrating a charged block in deep space.

Thank you for sharing your experiment and posing these interesting questions. It is always exciting to think about the potential applications and consequences of scientific phenomena.
 

FAQ: Can a Vibrating, Charged Block in Deep Space Produce Radio Waves?

1. What is the purpose of vibrating a charged block?

The purpose of vibrating a charged block is to study the behavior of charged particles under the influence of an external force, which in this case is the vibration. This can provide insights into the properties and interactions of charged particles, and can also be used for practical applications such as in particle accelerators.

2. How is the block charged before vibrating it?

The block can be charged in several ways, such as by rubbing it against another material, using an electrostatic generator, or exposing it to a high voltage source. The type of charging method used will depend on the material of the block and the desired level of charge.

3. What factors affect the vibration of a charged block?

The vibration of a charged block can be affected by various factors including the charge on the block, the mass and density of the block, the surface on which it is placed, and the strength and frequency of the vibration. These factors can influence the motion and behavior of the charged particles within the block.

4. What are the potential dangers of vibrating a charged block?

Vibrating a charged block can pose potential hazards such as electric shock, especially if the block is highly charged. It is important to take necessary precautions and follow proper safety protocols when handling charged blocks to avoid any accidents or injuries.

5. Can vibrating a charged block cause it to lose its charge?

Yes, vibrating a charged block can cause it to lose its charge over time. This is because the vibration can cause the charged particles within the block to move and redistribute, eventually neutralizing the overall charge. Additionally, if the block is in contact with a surface, the charge can also be dissipated through the surface due to friction.
