Those who are looking for an answer to the question «Why is light sometimes described as a wave and sometimes as a particle?» often ask the following questions:
👋 Light is sometimes described as a wave and sometimes as a particle give evidence to support the wave nature of light?
Light is sometimes described as a wave and sometimes as a particle. Give evidence to support the wave of natural light
- Is light wave or particle?
- How is a particle described by a wave function?
- How is light particle and wave?
👋 A particle is described by the wave function?
- The wave function of a particle, at a particular time, contains all the information that anybody at that time can have about the particle. But the wave function itself has no physical interpretation. It is not measurable.
👋 Are light particle or wave?
Light can be described both as a wave and as a particle. There are two experiments in particular that have revealed the dual nature of light. When we're thinking of light as being made of of particles, these particles are called “photons”. Photons have no mass, and each one carries a specific amount of energy.

Light is sometimes described as a wave and sometimes as a particle because light obviously travels as a wave. It is considered a particle because of the photons. A photon is an elementary particle, the quantum of light and all other forms of electromagnetic radiation, and the force carrier for the electromagnetic force. So therefore, it is a particle and that is why light is considered both a wave and a particle.

Christian Huygens, who was a contemporary of Isaac Newton, suggested that light travels in waves. Isaac Newton, however, thought that light was compsed of particles that were too small to detect individually. In 1801 a physicist in England, Thomas Young, performed an experiment that showed that light behaves as a wave.Why is light described as a wave?
Light behaves as a wave - it undergoes reflection, refraction, and diffraction just like any wave would.Is a light a particle or wave?
Light Is Also a Particle!
Now that the dual nature of light as "both a particle and a wave" has been proved, its essential theory was further evolved from electromagnetics into quantum mechanics. Einstein believed light is a particle (photon) and the flow of photons is a wave.
Is light a particle or a wave?
- "Light" is both a particle and a wave (the photon, like all other elementary particles, can be understood as a localized vibration in its quantum field that can be measured as particle-like or wave-like).
It's both. It will behave like a particle in some instances, and like a wave in others. This phenomenon is called particle-wave duality. Links can be found below for more information. Use the link to the related question for a modest explanation that steps through a couple of experiments demonstrating the ideas.
Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye (about 400-700 nm, or perhaps 380-750 nm). In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.Four primary properties of light are:
- Frequency or wavelength
- In other words, light was behaving as a particle in these experiments. So, different kinds of physics experiments were revealing different kinds of properties of light. Sometimes, light acted like a wave, and sometimes, light acted like a particle.
- In an approximate way, light is botha particle and a wave. But in an exact representation, light is neither a particle nor a wave, but is something more complex. As a metaphor, consider a cylindrical can of beans.
Light Is Also a Particle!
Einstein believed light is a particle (photon) and the flow of photons is a wave. The main point of Einstein's light quantum theory is that light's energy is related to its oscillation frequency.
Quantum mechanics tells us that light can behave simultaneously as a particle or a wave… When UV light hits a metal surface, it causes an emission of electrons. Albert Einstein explained this "photoelectric" effect by proposing that light – thought to only be a wave – is also a stream of particles.What is the wave particle of light?
- Wave-Particle Duality of Light Quantum theory describes that matter, and light consists of minute particles that have properties of waves that are associated with them. Light consists of particles known as photons and matter are made up of particles known as protons, electrons, and neutrons.
- The wave particle duality of light means that light exhibits properties of classical waves in some cases and properties of classical particles in others. The fringing effect that results from firing single photons through a double slit is the most famous demonstration of this duality.
How does light behave like a particle?
- Light as a Particle. Light behaves mainly like a wave but it can also be considered to consist of tiny packages of energy called photons. Photons carry a fixed amount of energy but have no mass. The energy of a photon depends on its wavelength: longer wavelength photons have less energy and shorter wavelength photons have more.
Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM - you have light.Can a massive particle be described by its wave or behaviour?
- The result demonstrates that it does not make sense to decide whether a massive particle can be described by its wave or particle behaviour until a measurement has been made. The techniques used could have practical applications for future physics research, and perhaps for information theory.
- Ultimately, say our hosts, you can call light both a particle and wave, and you'd be correct on some level. But as for fully explaining how light works, we're still working on it. Light's particulate behavior becomes more evident depending on where you're observing it.
- Similarly, light sometimes acts like a wave and other times acts like a particle but is in reality something more complex. Public Domain Image, source: Christopher S. Baird. Light sometimes acts like a wave and sometimes acts like a particle, depending on the situation.
Both. E = mc2(squared) wave is an energy form while m is mass (particle) einstein proved that light acts as wave and particle at the same time.
So how does light travel? Basically, traveling at incredible speeds (299 792 458 m/s) and at different wavelengths, depending on its energy. It also behaves as both a wave and a particle, able to propagate through mediums (like air and water) as well as space.How is light a particle and a wave?
Einstein believed light is a particle (photon) and the flow of photons is a wave… The various properties of light, which is a type of electromagnetic wave, are due to the behavior of extremely small particles called photons that are invisible to the naked eye.How is light a wave and a particle?
- The dual nature of light is wave-particle duality. Some experiments prove that light possesses characteristics of a wave while other experiments prove light is a particle. Light is neither considered a wave nor a particle, instead it has characteristics of both a wave and a particle.
