I am in my last year of school (12th grade in Germany) and the presentation is supposed to be about 10 minutes long. It is for my oral examination in physics (called Abitur, like A-levels in England or finals in the USA)malawi_glenn said:What academic level is this for, and how long is your presentation meant to be?
If you can make sense of this wiki article then there's enough there for a short presentation on the TWT. Ask here for a 'translation' of the more obscure bits but it really is a very straightforward device to get the idea of.nrckls said:I am in my last year of school (12th grade in Germany) and the presentation is supposed to be about 10 minutes long.

Where do the 'waves' come into it - except for the oscillating magnetic field and the deflection? I guess that, bearing in mind the level of the exercise, the idea of an oscillating field and scanning would be enough for a useful ten minutes of talk.tech99 said:How about describing the cathode ray tube?

The connection between oscillations/waves and particles in EM fields is that particles can exhibit wave-like behavior, and waves can interact with particles. This is known as wave-particle duality and is a fundamental concept in quantum mechanics.
Oscillations/waves in an EM field can exhibit a variety of behaviors, including reflection, refraction, diffraction, and interference. These behaviors are determined by the properties of the EM field and the medium through which the waves are traveling.
Exploring the intersection of oscillations/waves and particles in EM fields allows us to better understand the behavior of matter and energy at a fundamental level. This knowledge has practical applications in fields such as electronics, telecommunications, and quantum computing.
EM fields can exert forces on particles, causing them to accelerate or change direction. These fields can also affect the energy levels and properties of particles, leading to phenomena such as the photoelectric effect and the emission of light.
While we have a good understanding of the behavior of particles in EM fields, predicting and controlling their behavior at a quantum level is still a challenge. However, advancements in technology and research are helping us gain a deeper understanding and control over these phenomena.
