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.

Which theory of light is the photon more consistent with the wave theory or the particle theory?
The photon is more consistent with the particle theory of light, as it is a discrete bundle of electromagnetic energy. However, the wave-particle duality principle states that light can exhibit both wave-like and particle-like behavior depending on the experimental setup.
Is Compton effect support the wave theory of light or particle theory?
The Compton effect supports the particle theory of light, as it demonstrates that photons (particles of light) can interact with matter like particles and exhibit particle-like behavior by transferring momentum to electrons during scattering. This is not consistent with the wave theory of light, which views light as a continuous wave rather than individual particles.
Who first propose particle theory of light?
The particle theory of light was first proposed by Sir Isaac Newton in the 17th century. He suggested that light is made up of tiny particles called corpuscles. This theory was later challenged by the wave theory of light proposed by Christian Huygens.
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 was wave theory of light inadequate and was rejected?
The wave theory of light was inadequate because it couldn't explain certain phenomena like the photoelectric effect and blackbody radiation. These discrepancies led to the development and acceptance of the particle theory of light, which eventually paved the way for the quantum theory of light.
What physicist was the chief architect of the particle theory of light?
It was Max Planck who used the particle theory of light.
How is the quantum theory of light a combination of particle theory of light and wave theory of light?
The quantum theory of light unifies the particle theory of light (photons) and wave theory of light by treating light as both particles and waves. Photons are quantized packets of energy that exhibit particle-like behavior, while light waves exhibit wave-like behavior with properties such as interference and diffraction. Quantum theory provides a framework to understand the dual nature of light.
Is the emission of electromagnetic radiation by an excited atom a wave or particle theory?
wave theory of light
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.

Enumerate the theories of nature of light?
Wave theory - light is a type of electromagnetic wave proposed by scientists like Maxwell and Huygens. Particle theory - light consists of particles called photons, advocated by scientists like Einstein and Planck. Wave-particle duality - the concept that light exhibits both wave-like and particle-like behavior, proposed by quantum mechanics.

What is the difference between ray theory and mode theory of light?
Ray theory of light describes light propagation as a series of straight lines or rays, ignoring the wave nature of light. Mode theory, on the other hand, considers light as propagating in different modes within waveguides or optical fibers, taking into account the wave properties of light. Ray theory is useful for geometrical optics, while mode theory is more applicable to waveguides and optical fiber communications.
What law explains dual nature of light?
The wave-particle duality theory. This explains why sometimes light appears to travel as a wave, and why sometimes it appears to travel as a particle.
