The photoelectric effect is a quantum electronic phenomenon in which electrons are emitted from matter after the absorption of energy from electromagnetic radiation such as x-rays or visible 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.
The quantum theory of light explains the results of experiments by treating light as particles called photons. These photons exhibit wave-particle duality, where they can behave as both particles and waves. This quantum nature of light helps explain phenomena such as interference patterns and the photoelectric effect.
Neither, try again.
Yes, the Particle Model can explain refraction by considering light as a stream of particles (photons) that change speed and direction when passing through different mediums, causing the bending of light rays.

No. To explain the photoelectric effect, you have to think of light as a particle, not a wave. The fact that light can be both a wave and a particle is part of quantum mechanics, not classical physics.
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.
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.
Einstein employed the particle-like nature of light, known as photons, to explain the photoelectric effect. He proposed that light is made up of discrete packets of energy (photons) that can transfer their energy to electrons in a material, causing them to be emitted. This idea helped to explain why the photoelectric effect occurred instantaneously at certain frequencies of light, as the energy of individual photons is proportional to their frequency.
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.
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.
Einstein first proposed the idea that light consists of particles called photons to explain the photoelectric effect and the results of double-slit experiments. He suggested that photons carry discrete amounts of energy and that they interact with matter as individual particles.
Einstein first proposed the idea of photons as discrete packets of light energy to explain the photoelectric effect. According to his hypothesis, light is composed of individual particles called photons that transfer their energy to electrons upon striking a material surface. Additionally, Einstein's explanation of the double-slit experiments involved the concept of wave-particle duality, stating that light exhibits both wave-like and particle-like properties.
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.
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.
