# Does string theory explain wave-particle duality?

## Does string theory explain wave-particle duality?

The wave particle duality (or position momentum commutation relations) remain the same in string theory as in usual quantum mechanics of a point particle. The only difference is that now the position and momentum operators tell respectively the average position and momentum of the string.

What is wave-particle duality in physics?

In physics and chemistry, wave-particle duality holds that light and matter exhibit properties of both waves and of particles. A central concept of quantum mechanics, duality addresses the inadequacy of conventional concepts like “particle” and “wave” to meaningfully describe the behaviour of quantum objects.

### What is wave theory and particle theory?

The theory is often called the wave-particle theory. It explains how electromagnetic radiation can behave as both a wave and a particle. Einstein argued that when an electron returns to a lower energy level and gives off electromagnetic energy, the energy is released as a discrete “packet” of energy.

Did Einstein discovered wave-particle duality?

On the basis of experimental evidence, German physicist Albert Einstein first showed (1905) that light, which had been considered a form of electromagnetic waves, must also be thought of as particle-like, localized in packets of discrete energy.

#### Why does wave-particle duality exist?

According to string theory the wave particle duality exists because electrons are actually standing waves, so electrons can act as waves.

What is difference between particle and wave?

The difference between the particle and waves are: The particle is defined as the small quantity of matter under the consideration. The wave is defined as the propagating dynamic distrubance. The energy of the wave is calculated based on the wavelength and velocity.

## Can a human be diffracted?

If we assume that the human body can be treated as a single particle at the centre of mass, then we can tackle this problem. Optimal diffraction occurs when the wavelength is equal to the size of the aperture. This gives a velocity of 1.6565×10−35 metres per second.

Is there such a thing as wave particle duality?

All we can say is that wave-particle duality exists in nature: Under some experimental conditions, a particle appears to act as a particle, and under different experimental conditions, a particle appears to act a wave.

### When did Christiaan Huygens and Isaac Newton propose wave particle duality?

Wave-Particle Duality in Light In the 1600s, Christiaan Huygens and Isaac Newtonproposed competing theories for light’s behavior. Huygens proposed a wave theory of light while Newton’s was a “corpuscular” (particle) theory of light.

When does a particle act as a wave?

Summary Wave-particle duality exists in nature: Under some experimental conditions, a particle acts as a particle; under other experimental conditions, a particle acts as a wave. Conversely, under some physical circumstances, electromagnetic radiation acts as a wave, and under other physical circumstances, radiation acts as a beam of photons.

#### How does the double slit experiment support the wave theory?

Diffraction had been observed, for one thing, which it had trouble adequately explaining. Thomas Young’s double slit experiment resulted in obvious wave behavior and seemed to firmly support the wave theory of light over Newton’s particle theory. A wave generally has to propagate through a medium of some kind.
