Wave and particle

  1. Oct 28, 2004 #1
    scitensit in 20th centry suggest that

    wave can behaviour like a particle

    and particle can behave like a wave

    for first propose wave can behave like a particle

    but does it ever collide?

    e.g photons

    Waves aren't said to collide, they are said to interfere. This is the hallmark of waves. Interference is basically the interaction of waves which gives rise to interesting phenomena.

    Photon-photon collision IS predicted within the Standard Model. It has not been possible to do this experimentally yet because the cross-section is extremely small. In fact, the appreciable range where this can start to be detected is for a gamma-gamma collision. There are many facilities (such as TESLA at DESY) throughout the world that are designing their particle colliders to also able to such measurements.

    See, the thing is, that it depends on freqency . If the freqency of a wave is very high the wave behaves as a particle and at very high freqencies it shows no chareterstics of a wave.

    So, basically as the guyz before me have stated, there is no collision in waves there is interfearence, you might want to look up the young's double slit experiment to get a clearer view.

    Oh and by the way, i'm not sure, if you asked about waves with waves or waves with particles. And if you asked about waves and particles, then its a good question. Well, a wave at low frequencies would probably just be opposed by mass but with a photon that has no mass, i'm pretty unsure abt it, could someone else explain that? What does happen when a wave and a photon are pitted against each other?

    ic ic thx also from ""the thinker"

    that usually wave as particle collides when at high frequency, such as gamma ray =)
