          Thank you for redirecting there. I actually had physics classes in my higher education but I’m a bit confused on when particule behavior and wave behavior manifest now that’s it’s been some years

    Actually everything is both, even you are a wave, just a really shitty one that is much closer to a partical

      Are you saying all matter is merely energy condensed to a slow vibration, that we are all one consciousness experiencing itself subjectively, there is no such thing as death, life is only a dream, and we are the imagination of ourselves?

    Ok so a wave is the physical expression of energy transferring through a medium

    Ocean waves are kinetic energy transferring from water molecule to water molecule, sound is high frequency waves moving through a transmissible medium in a way we can perceive as noise, etcetera.

    “Light is a wave and a particle” refers to the fact that since photons travel in a probability wave until perceived, they are capable of being their own medium for electromagnetic energy.

    This is why light can travel in a vacuum where other wave based phenomenon cannot, light comes with its own medium to travel through the void with.

      This kinda falls apart once you realize that all small particles (atoms, electrons, molecules, etc) have wave particle duality.

        Yes but its the best “in English please” explanation I can come up with.

        Otherwise we’re going to have to start talking about the non-zero odds a beautiful woman is going to materialize and accept the second ice cream cone and nobody has the time for that outside of a laboratory or lecture hall.

    The post title got me the most. Sounds like something you can’t say, like you’ll get arrested over it.

    After listening to 100s of science podcasts, watching 1000s of science vids on YT, and sleeping on a Neil Degrasse Tyson pillow I still don’t understand how something can be both a particle and a wave. Sounds made up, like by a lazy SWE

      It’s easier once you understand that they are not both, particles are actually a type of wave 🙃

      I think the best way of thinking about it is that it’s neither. Vaguely speaking, “quantum stuff” can be described very well by math, and this math has some elements of “waveness” (think wave equations, interference) and “particleness” (think ladder operators or maybe position eigenstates). But that doesn’t mean it’s one, the other, or even both — it’s described by some math, and that math is agnostic as to what you call it.

      In our macroscopic experience it’s easy to divide the world into these two convenient buckets, but the reality is different.

      Personally I think this weirdness is exploited by popsci to get more clicks, but maybe that’s just my jaded opinion after years of grad school…

    As a general rule, if you set out to design an experiment to show that light is a wave (or a particle), it will behave as a wave (or a particle). The more fun thing is to show that it behaves as both, which can be done by utilizing sensitive detectors and exploiting interference patterns.

      A photon is a quanta of light. Our picture of light, to this point, has been that of a wave. Wave-like characteristics are responsible for diffraction and refraction. However, light is absorbed and emitted one photon at a time.

      I knew some new study would betrayal me, well I still wave my particle…

      Quanta is just a word (related to quantity) as in: “smallest divisible quantity of”

      So in the case of light we would be talking about photons, which are a quanta of light (e.g. discrete “packets” of light).

      Light behaves as a wave, e.g. we can talk about the frequency of light. But it’s also pretty different from macroscopic waves e.g. it’s not accurate to think of them as what your see on a typical sinusoid graph, as at that level things don’t really have a fixed shape or position, we’re talking more about areas where they “probably” are (see: superposition, HUP etc)

      It’s useful to think of light in terms of discrete photons for a number of reasons, e.g. in pair production, 1 gamma photon would be sufficient to create 1 electron/positron pair.

      Photons also exhibit other particle-like behaviour despite having no rest mass. But the idea of rest mass becomes less significant at that level anyway as the line between energy and mass (e=mc²) gets blurred. And any sufficiently high energy object will likely exhibit some massive properties (hence why we tend to use MeV - a measure of energy - instead of a measure of mass, even when performing calculations with massive particles such as electrons.
