How does the wave particle duality explain the double-slit experiment and its results?

An alternative to the standard understanding of quantum mechanics, the De Broglie–Bohm theory states that particles also have precise locations at all times, and that their velocities are defined by the wave-function.

How does the double-slit experiment prove that light is a wave?

In quantum mechanics the double-slit experiment demonstrated the inseparability of the wave and particle natures of light and other quantum particles. If classical particles are fired in a straight line through a slit they will all strike the screen in a pattern the same size and shape as the slit.

How does quantum mechanics describe light?

Quantum theory tells us that both light and matter consists of tiny particles which have wavelike properties associated with them. Light is composed of particles called photons, and matter is composed of particles called electrons, protons, neutrons.

What is the concept of particle/wave duality of light in relation to the photoelectric effect?

wave-particle duality: A postulation that all particles exhibit both wave and particle properties. It is a central concept of quantum mechanics. Electrons are emitted from matter when light shines on a surface . This is called the photoelectric effect, and the electrons emitted in this manner are called photoelectrons.

How do the wave and particle natures of light compare?

The key difference between wave and particle nature of light is that the wave nature of light states that light can behave as an electromagnetic wave, whereas the particle nature of light states that light consists of particles called photons.

How does particle nature of light explain photoelectric effect?

The photoelectric effect supports a particle theory of light in that it behaves like an elastic collision (one that conserves mechanical energy) between two particles, the photon of light and the electron of the metal. The minimum amount of energy needed to eject the electron is the binding energy, BE.
