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 behavior of light evidence for a wave model of light?
One evidence for the wave model of light is interference, where light waves can combine constructively or destructively to form patterns of bright and dark regions. Another evidence is diffraction, where light waves bend around obstacles or openings. Lastly, the polarization of light can also be explained by the wave model, as it describes how light waves vibrate in a specific plane.
What describes light traveling as a wave?
Light traveling as a wave means that it exhibits properties such as interference, diffraction, and polarization. These properties can be explained by the wave nature of light, where it propagates through oscillations of electric and magnetic fields perpendicular to each other and to the direction of travel.
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.
What phenomenon cannot be explained on the basis of the wave theory of light?
The phenomenon of photoelectric effect cannot be explained on the basis of the wave theory of light. The wave theory predicts that the energy of a light wave is proportional to its intensity, whereas the photoelectric effect depends on the frequency of light.

Phenomena such as diffraction and interference can be most easily explained in terms of what?
Phenomena like diffraction and interference can be most easily explained using the wave nature of light. These phenomena occur when light waves interact with each other or with obstacles in their path, leading to the observed patterns of light and dark fringes. The behavior of light as a wave can explain the way it diffracts around obstacles and interferes constructively or destructively to produce interference patterns.
What two waves can light be described as?
Light can be described as both an electromagnetic wave and a transverse wave. Its behavior can be explained by both wave theories.
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.
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.
Which cannot be explained with wave theory of light?
Wave-particle duality, which suggests that light sometimes behaves like a wave and other times like a particle, cannot be fully explained by the wave theory of light. The photoelectric effect and Compton effect also challenge pure wave theory by demonstrating particle-like behavior of light.
Why the wave model for radiation does not account for the photoelectric effect?
Predictions of the wave model: Energy of light was dependent on the amplitude of the light wave, which was manifested as the brightness of the light. Higher amplitude (brighter) light would cause the ejected electrons to be more energetic. Colour of light was dependent on the frequency of the light but frequency had no bearing on the energy of the ejected photons. Predictions of the photon model: Both the energy of light and the colour of light was dependent on the frequency of the photons. Higher frequency would cause the the ejected electrons to be more energetic. The number of photons was manifested as the brightness of the light. Higher number of photons (brighter) light would cause the ejected electrons to be more numerous (higher current). Observations from the photoelectric effect experiment: Ejected electron energy was directly related to the frequency of the light and brighter light resulted in higher current. These observations were explained by the photon model and could not be explained with the wave model.
What model of light does the polarization of light support Explain?
The polarization of light is best supported by the wave model of light, which describes light as an electromagnetic wave with oscillating electric and magnetic fields perpendicular to the direction of propagation. In the wave model, polarization occurs when the electric field oscillates in a specific orientation, leading to light waves that are aligned in a particular way. This model explains how polarizing filters can selectively block certain orientations of light waves, demonstrating the wave-like nature of light.
