2025年1月11日 · My son is in year 7. I received a test paper and his answers. Unfortunately, we don't have the correct answer for some questions. I have attached the screenshot. The topic is particle model (year 7). I would appreciate your help. This is not a homework question but I need your expert advice so I can help him. Please help with following ...

2019年2月8日 · Particle physics is the study of particles, their properties and how they interact. There are a couple of ways you can model particles, but the most general theory for doing so is Quantum Field Theory, which is used when the quantum nature of particle must be taken into account and they are moving at relativistic speeds.

2021年9月15日 · FAQ: Particle and wave model understanding -- help please 1. What is the particle and wave model? The particle and wave model is a theory that explains the behavior of particles and waves at the microscopic level. It states that particles, such as atoms and subatomic particles, can exhibit both particle-like and wave-like properties. 2.

2014年6月17日 · When Einstein discovered photo-electric effect (and thus the particle nature of light), people realized that may be it is the dual nature of light which made Planck's formula successful. The only thing which I cannot understand here is that how according to R-J, total energy of EM radiation in equilibrium comes out infinite.

2025年1月10日 · No, this is not correct. In FRW models of the universe as a whole, the "dust" that models matter (positive energy density, zero pressure) is not a model in which galaxies are point particles. It is a model where the average distribution of matter in the universe is a …

2013年1月2日 · How do the results of performing Young's experiment with x-rays and then high speed electrons support the wave-particle model? The Attempt at a Solution The experiment showed that an electron traveling at high speeds are capable of making interference patters, which is a characteristic of waves.

2021年3月29日 · A fairly advanced reference is the second edition of "The Standard Model and Beyond" (2017) by Paul Langacker. At the about level of Griffiths there are the excellent "Modern Particle Physics" (2013) by Mark Thomson, and the interesting "Advanced Concepts in Particle and Field Theory" (2015) by Tristan Hubsch.

2015年5月4日 · The particle is more likely to be found in certain positions than others, depending on its energy. There are “blind spots”, or places where the particle can never be detected. The energy of the particle must obey a discrete set of energy levels. The particle can not have zero energy, so it is always moving.

2009年2月6日 · In a classical model [itex]-\phi(x)[/itex] stands for the amplitude of the field. The amplitude can be all sorts of things, most prominent example being the displacement of an atom with respect to some mean lattice.

2025年1月3日 · I just wanted to know how they go about demonstrating a particle being in superposition of both spin up and down relative to some axis. OK, it probably cannot be done with just one any more than you get an interference pattern by sending a single photon through the slits. I get that much. I...
