The wave model cannot explain the photoelectric effect because it assumes that energy is transferred continuously, while the photoelectric effect shows that electrons are emitted instantaneously when light of a certain frequency hits a material. This is better explained by the particle nature of light, as described by the photon theory.

Which property of light is not explained ny the wave model of light?
The wave model of light cannot fully explain the photoelectric effect. This phenomenon involves the emission of electrons from a material when it is exposed to light, and it requires the particle-like behavior of light to be understood.
What model of light helps explain the photoelectric effect?
The photoelectric effect is explained by the particle-like behavior of light, as described by the concept of photons in quantum theory. According to this model, light is composed of discrete packets of energy called photons that transfer their energy to electrons, causing them to be ejected from a solid surface.
The wave model of light does not explain?
The wave model of light does not explain certain behaviors of light, such as the photoelectric effect, where light behaves as discrete particles (photons) instead of a continuous wave. This discrepancy led to the development of the dual nature of light, which incorporates both wave and particle properties to fully describe its behavior.
The particle model describes light as?
The particle model describes light as a stream of tiny particles called photons. Photons have no mass, but they carry energy and momentum. This model helps explain some behaviors of light, such as the photoelectric effect.
Is there a phenomenon that does not support the wave nature of light?
Yes, the photoelectric effect is a phenomenon that does not support the wave nature of light. It demonstrates particle-like behavior of light as photons transfer their energy to electrons in a material, causing them to be emitted. This phenomenon cannot be explained using a wave model of light.

What properties of light cannot be described by using the wave model of light?
The particle nature of light, as described by the photon theory, cannot be fully explained by the wave model of light. The wave model also cannot account for certain phenomena such as the photoelectric effect and the behavior of light in very small scales, which require a particle-like description of light.
Compare wave and particle models of light. What phenomena can only be explained by the particle model?
The wave model of light describes light as an electromagnetic wave that exhibits properties like interference and diffraction. The particle model of light, on the other hand, describes light as a stream of particles called photons. Phenomena like the photoelectric effect and Compton scattering can only be explained by the particle model of light, where light behaves as discrete particles (photons) interacting with matter.
What are three deficiencies of the wave model of light related to lights interaction with matter?
The wave model fails to explain the photoelectric effect, where light shining on a metal surface emits electrons. It cannot account for the discrete emission spectra from excited atoms, known as the line spectra. The wave model does not explain the wave-particle duality of light, as observed in phenomena such as the double-slit experiment.
What is the particle model of light?
The particle model of light, known as the photon theory, describes light as being made up of individual packets of energy called photons. Photons have characteristics of both particles and waves, depending on how they are observed. This model helps explain phenomena such as the photoelectric effect and the behavior of light in certain experiments.
What model of light describes the behaviors of light when it acts as a stream of photons?
The model that describes light as a stream of photons is the particle model of light. In this model, light is considered to be made up of discrete packets of energy called photons, each with a specific wavelength and frequency. This model helps explain phenomena such as the photoelectric effect and the quantization of light energy.
What experiments led to bohrs model?
Experiments like the photoelectric effect and atomic emission spectra provided evidence that electrons exist in discrete energy levels. These findings challenged the classical model of the atom, leading to Niels Bohr proposing his model in 1913 to explain the quantization of electron energy levels in atoms.
The wave model of light does not explain what?
It does not explain the photoelectric effect. According to the wave theory, given light of sufficient intensity, electrons should be emitted from the surface of a metal. What is observed though, is that given light of sufficient frequency, electrons will be emitted from the metal surface independent of intensity. If the frequency is too low, electrons will NOT be emitted even if the highest intensity of light was used. Albert Einstein suggested that it would be possible to explain the photoelectric effect if light was considered to be made up of particles instead of waves. The energy of the particles of light, called photons, would be proportional to the frequency of the light. Electrons would be emitted from the metal only if the energy of ONE photon was sufficient for the electron on the metal surface to break bonds and escape from the surface. Otherwise, the photons will rebound on the metal surface with no emission of electrons. Einstein 'mathematised' the photoelectric effect in the following equation: hf = Ekmax + o where h is the planck constant f is the frequency of the radiation Ekmax is the maximum kinetic energy of the emitted electrons o is the work-function energy, that is the minimum energy required for the electron to escape from the metal surface. Note: hf is the energy of a photon. It was for the explanation of the photoelectric effect that Einstein was awarded the Nobel prize in Physics in 1921. (and not for his still greater discoveries in relation to relativity)
