Any EM field pattern propagates at a finite velocity, taking some time to travel over a distance. Also, the pattern of that EM field is preserved as it travels.Helicobacter said:1. How do we know EM radiation is a wave?
Wave-particle duality is the idea that all matter and energy can exhibit both wave-like and particle-like behavior. This means that objects, such as electrons and photons, can act as both waves and particles depending on the experimental setup.
Wave-particle duality challenges the traditional concept of determinism, which states that all events are caused by prior events and can be predicted with certainty. The uncertainty principle, a fundamental principle of quantum mechanics, states that it is impossible to simultaneously know the precise position and momentum of a particle. This means that determinism cannot fully explain the behavior of particles at the quantum level.
The double-slit experiment is one of the most famous experiments that demonstrates wave-particle duality. In this experiment, a beam of particles, such as electrons, is passed through two slits and creates an interference pattern, similar to what would be expected of waves. Other experiments, such as the photoelectric effect and the Compton effect, have also confirmed the duality of particles.
Wave-particle duality has forced scientists to rethink their understanding of the physical world. It has shown that the behavior of particles at the quantum level cannot be fully explained by classical physics. This has led to the development of quantum mechanics, which provides a more accurate description of the behavior of particles at the atomic and subatomic level.
No, the wave-like and particle-like behavior of a particle cannot be observed simultaneously. This is due to the uncertainty principle, which states that the act of measuring one property of a particle, such as its position, will inherently change another property, such as its momentum. Therefore, it is impossible to observe both behaviors at the same time.
