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.

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.
Light behaves primarily as a wave when it?
Light behaves primarily as a wave when it undergoes phenomena such as diffraction and interference. These behaviors are best explained by wave theory rather than particle theory.
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 observations or experiments do not show light behaving as a classical wave?
Certain experiments such as the photoelectric effect and the Compton effect cannot be explained by classical wave behavior. The quantized nature of light revealed by these experiments led to the development of the quantum theory of light.
Transmission by a lens is best explained by what theory?
Transmission by a lens is best explained by the wave theory of light, which posits that light travels in waves and undergoes refraction as it passes through a lens. The wave theory helps explain how light bends and focuses through different media, such as lenses, due to variations in the speed of light.

What are some properties of light that can be best explained by the wave theory?
Properties of light that can be best explained by the wave theory include interference, diffraction, and polarization. Wave theory describes how light waves can interact with each other to produce interference patterns, how they bend around obstacles and spread out when passing through small openings (diffraction), and how their oscillations can be oriented in specific directions (polarization).
What did Young's observation of an interference pattern for light show about the nature of light?
It shows that light behaves as a wave phenomenon. Interference cannot be explained using a particle theory. http://www.physicsclassroom.com/class/waves/Lesson-3/Interference-of-Waves
What does not support the wave nature of light?
The photoelectric effect does not support the wave nature of light. This phenomenon can only be explained by the particle nature of light, as described by Albert Einstein in his theory of photons.
Why can't the wave model cannot explain the photoelectric effect?
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.
Limitations of Huygen's wave theory of light?
Huygens' wave theory of light cannot explain phenomena like polarization and interference accurately. It also fails to predict some experimental observations, such as the photoelectric effect. Additionally, the theory could not fully account for the speed of light in a vacuum.
What waves does light travel in?
Light is theorized as both a particle and a wave. Since it is similar to the electron in this way, the Double-Slit Experiment showed that there is a concentration of charge in many areas, but when closely examined, the electron only passes through one of the two slits. Light travels in both a wave and a particle in this sense. Things such as interference, diffraction and polarization cannot be explained by light being a particle as the photoelectric effect cannot be explained by light being a wave, in addition to reflection and refraction both able to be explained by either a wave or a particle.
How does wave theory explain the photoelectric effect?
Wave theory cannot fully explain the photoelectric effect, as it predicted that the intensity of light, not its frequency, would determine the kinetic energy of ejected electrons. The photoelectric effect is better explained by the particle nature of light, where photons carry discrete amounts of energy that are transferred to electrons upon impact, leading to their ejection from a material.
