Wave-Particle Duality

Postby Qilan Li 4I » Sat Oct 12, 2019 12:36 am

Can someone explain more in-depth what wave-particle duality is and how light can be both?

In quantum mechanics, wave-particle duality is seen in objects with small masses in which they can sometimes act as waves or particles. For example, an electron with wave-particle duality can be released and travel outward emitting a wave, but as it reaches a surface that it can bounce off, it will only hit in one place, similar to a particle.
Due to the fact that light is a type of electromagnetic wave, and the idea that light consists of extremely small particles called photons consisting of energy, light has a wave-particle duality. The fact that light is a wave came from Young’s Interference Experiment where light or waves pass through a double slit and add or cancel each other out. Through Einstein's photoelectric effect, he explains how light is a particle with energy (photons) in relationship to the wavelength.
