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.
What is the difference between particle and wave theory of light?
Particle theory of light, proposed by Isaac Newton, views light as composed of discrete particles called photons. Wave theory of light, formulated by Thomas Young, describes light as a wave propagating through a medium. The wave theory better explains phenomena like interference and diffraction, while the particle theory accounts for aspects such as the photoelectric effect.
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.
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 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.

Is there any importance in photoelectric effect?
One of the most revolutionary concepts in physics is the photoelectric effect. The photoelectric effect occurs when radiant energy is impinged on various metals and electrons are ejected from the metal surface. The ejected photoelectrons have a certain kinetic energy which can be measured by the produced voltage. Photoelectric current cannot be explained by the wave theory as diffraction and interference can, however. The photoelectric effect is important because it revealed some of the limitations of the classical wave theory and it gave closer insight into the nature of light- namely the quantization as photons.
Who hypothesized that light can behave as a particle called photon?
Albert Einstein was the scientist who hypothesized that light can behave as a particle called a photon in his theory of the photoelectric effect, for which he was awarded the Nobel Prize in Physics in 1921.
Who developed the theory of photons being quantized?
Einstein, and he used the theory to describe the photoelectric effect.
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.
What did Einstein two papers explain?
Einstein's two papers explained the theory of special relativity and the photoelectric effect. The paper on special relativity introduced the concept of space-time and the relationship between space and time, while the paper on the photoelectric effect explained how light behaves as both a wave and a particle.
What discovery resulted from the photoelectric effect?
The discovery resulting from the photoelectric effect was that light can behave as both a wave and a particle. This finding led to the development of the quantum theory of light, which laid the foundation for quantum mechanics.
Discovery of particle theory of light?
The particle theory of light, which suggests that light is made up of small particles called photons, was first proposed by Albert Einstein in 1905 to explain the photoelectric effect. This theory revolutionized our understanding of light and helped to explain phenomena that the wave theory of light could not account for. Today, the particle-wave duality of light is a fundamental concept in quantum mechanics.
