What Causes the Formation of Plasma in a Microwave?

AI Thread Summary
Creating plasma in a microwave involves ionizing the air surrounding a lighted match placed in a cork holder, covered by a glass beaker. The experiment results in a visible blob of plasma at the top of the beaker. While there was a humorous mention of Phosphorus and Potassium Chlorate in the match head, the consensus is that the plasma formation is primarily due to the ionization of air. The discussion highlights the simplicity of the experiment and the basic principles of plasma formation. Overall, the focus remains on the ionization process as the key factor in creating plasma.

Hi everyone,

I am about to enter a local Science Fair and my project revolves around creating plasma in a microwave. This is a great experiment, all you do is stick a lighted match in a cork, (or something to hold the match in place) put it in the microwave with a glass beaker over the match and switch it on. The resulting effect is a large 'blob' of plasma in the top of the beaker. But I was wondering, when this happens is it the air surronding the match being ionised, or is it the Phosphorus and and/or Potassium Chlorate in the match head?

Thanks in advance.

Well, even with my very minimal knowledge about plasma, I know that plasma is formed by ionized gas(air), nowhere in the Wikipedia page did it mention Phosphorus or Potassium Chlorate! That was a joke.. But really, I would say the air is being ionized if you truly have created plasma. My answer is probably not what you were looking for but I thought I'd give my two cents since nobody else has commented at the time I was composing this.

Thanks TheSatirist, you probably gave about 10 cents there, not just 2
 
Thread 'Simple math model for a Particle Image Velocimetry system'
Hello togehter, I am new to this forum and hope this post followed all the guidelines here (I tried to summarized my issue as clean as possible, two pictures are attached). I would appreciate every help: I am doing research on a Particle Image Velocimetry (PIV) system. For this I want to set a simple math model for the system. I hope you can help me out. Regarding this I have 2 main Questions. 1. I am trying to find a math model which is describing what is happening in a simple Particle...
I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
