Which model is light a wave model or particle model?

The particle model of light predicted that the speed of light would be faster in water than in air, and the wave model predicted the opposite. Therefore, the determination of the speed of light was seen to be a critical experiment in order to decide between the wave and particle models of light.

What experiments are best explained by the wave model of light?

A definitive experiment was Young’s double slit experiment, which demonstrated that light shined at two slits in a screen show an interference pattern characteristic of waves of light, rather than particles. The phase associated with a wave is also important in describing certain phenomena.

What is light described by the wave model?

Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM – you have light.

Which theory of light explains that light can be both a particle and a wave?

Einstein believed light is a particle (photon) and the flow of photons is a wave. The main point of Einstein’s light quantum theory is that light’s energy is related to its oscillation frequency.

Which phenomenon is best explained by the particle nature of light?

the photoelectric effect
A key experiment that was explained by Einstein using light’s particle nature was called the photoelectric effect. The photoelectric effect is a phenomenon that occurs when light shined onto a metal surface causes the ejection of electrons from that metal.

Which model of light best explains the photoelectric effect?

The model of light supported by the photoelectric effect is the (b) particle model of matter.

What is the wave-particle duality of light?

In physics and chemistry, wave-particle duality holds that light and matter exhibit properties of both waves and of particles. The idea of duality is rooted in a debate over the nature of light and matter dating back to the 1600s, when competing theories of light were proposed by Christiaan Huygens and Isaac Newton.

How does light behave like a wave and a particle?

Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. The energy of a photon depends on its wavelength: longer wavelength photons have less energy and shorter wavelength photons have more.

Which phenomenon supports the particle model of light?

The 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.
