The duality of light is mainly a concept, brought on by empirical evidence that suggested that light could behave and can much like both a wave and a particle.
It began with the wave theory of light. The wave theory predicted that light waves could interfere with each other like sound waves, and that light could be polarized, if it were a transverse wave. Thomas Young's two-slit experiment showed the diffraction of light. His experiments supported the theory that light consists of waves as waves were shown to have diffracted through slits.
Although the particle theory of light had been suggested before the wave theory, it was never taken seriously into account, until now. Experimental evidence of the photoelectric effect, by which light striking a metal surface ejected electrons from the surface, causing an electric current to flow across an applied voltage. Experimental measurements demonstrated that the energy of individual ejected electrons was proportional to the frequency, rather than the intensity, of the light. Furthermore, below a certain minimum frequency, which depended on the particular metal, no current would flow regardless of the intensity. These observations clearly contradicted the wave theory, and for years physicists tried in vain to find an explanation. In 1905, Einstein solved this puzzle as well, this time by resurrecting the particle theory of light to explain the observed effect.
Together, with more empirical evidence supporting both wave and particle characteristics, they formed the basis for wave-particle duality and much of quantum mechanics.
What else can I help you with?
Does light possesses photons and waves?
Yes, light exhibits characteristics of both photons and waves. It can behave as a stream of particles (photons) when interacting with matter, while also exhibiting wave-like properties such as interference and diffraction. This duality is known as the wave-particle duality of light.
When light is emitted as particles it is called?
When light is emitted as particles, it is called photons. Photons are the basic unit of light and have properties of both particles and waves.
What are the properties of photons?
Photons are elementary particles that have properties of both particles and waves. They have no mass, travel at the speed of light, and carry electromagnetic radiation. Photons can be absorbed or emitted by atoms, leading to phenomena like the photoelectric effect and the creation of light.
Is it true or false that light possesses two properties called photons and waves?
The statement "light possesses two properties: photons and waves" is not true because photons are not a property of light: they're the way light is emitted and absorbed. The correct statement is "light possesses two properties: particles and waves." Other properties of light include intensity, propagation direction, frequency, polarization. More information: Wave/Particle duality of light is one of the longest running paradoxes in Physics. It's wave characteristics, as described by Schrodinger function, are well proven. It's particle characteristics are also well evidenced though only directly at short ranges and lifetimes. The original assumption that all light comes in Photon particles with mass came from gravitational lensing,- light bent by large objects. We now better understand about curved space time curving everything, massive or not, but light is still described as wave bundle /corpuscles. The Photon is not a 'property', the two characteristics current physics uses are are 'waves' and 'particles'. 'Light' is simply a limited section of the energy wave spectrum that happens to be 'visible' to many creatures living on planet earth.

Tiny packets of light are called photons. They are the basic unit of light and possess properties of both particles and waves.
Is light matter?
No, light is not an example of matter. It is an example of electromagnetic waves. However, it is considered that light is composed of photons (massless particles) as well as waves by quantum physics.
What makes photons?
Photons are fundamental particles that make up light. They are produced when an atom releases energy in the form of electromagnetic radiation. Photons have dual properties of both particles and waves, as described by quantum theory.
Who concluded that particles can have some of the properties of light?
Albert Einstein concluded in his paper on the photoelectric effect that light behaves as particles. This led to the concept of photons, which are particles of light that have properties of both waves and particles.
Can electromagnetic waves can behave like what type of particles?
Electromagnetic waves can behave like particles known as photons. Photons are the quanta of light and exhibit both particle-like and wave-like properties.
Does light produce photons and waves?
yes
Is light only made out of photons or even just waves and how can we see waves in a form of light?
There are evidences that light is made up of particles called photons and even of waves. Light plays a dual nature. Some phenomenon like reflection and refraction can be explained on the basis of particles called photons while phenomenon like diffraction and polarization can be explained on the basis of wave theory of light. So, we can say that light is made up of particles as well as waves.
Photons of light?
... have roughly double the energy of photons of red light, because their frequency is roughly double the frequency of red-light photons. (That also means that their wavelength is roughly half the wavelength of red-light photons, but this fact doesn't help the current discussion at all.)
