Wave-Particle Duality: 20th Century Evidence

In summary, scitensit in the 20th century suggested that a wave can behave like a particle and a particle can behave like a wave. There is no collision between waves, but rather interference. However, photon-photon collision is predicted within the Standard Model and is being studied at facilities like TESLA at DESY. At high frequencies, waves can behave like particles and potentially collide, such as with gamma rays.

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 thanks also from ""the thinker"



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

What is wave-particle duality?

Wave-particle duality is the concept in quantum mechanics that states that particles, such as electrons, can exhibit both wave-like and particle-like behavior depending on how they are observed or measured.

Who discovered wave-particle duality?

The concept of wave-particle duality was first proposed by French physicist Louis de Broglie in 1924. However, it was not until the 20th century that experimental evidence was found to support this idea.

What is the double-slit experiment and how does it demonstrate wave-particle duality?

The double-slit experiment is a classic experiment in quantum mechanics that involves shooting particles, such as electrons, through two narrow slits in a barrier. The resulting pattern on a screen behind the barrier shows interference patterns, similar to what would be expected from waves. This demonstrates that particles can behave like waves, supporting the concept of wave-particle duality.

What other experiments have provided evidence for wave-particle duality?

In addition to the double-slit experiment, other experiments such as the Compton effect, which showed the wave-like behavior of photons, and the Davisson-Germer experiment, which demonstrated the diffraction of electrons, have provided evidence for wave-particle duality.

Why is wave-particle duality important?

Wave-particle duality is important because it helps us understand the behavior of particles at the quantum level, which is crucial for many modern technologies, such as transistors, lasers, and computer memory. It also challenges our traditional understanding of the universe and forces us to think about the fundamental nature of matter and energy.
