Give examples for dual nature of light?

Answer 1

The dual nature of light suggests that light exhibits the characteristics of both waves and particles. Light can seem to be particles in that it has discrete chunks (quanta, photons) of energy. Light can also seem to be waves, such as when you have light of one color go through two slits the light from the two paths interfere and cause bands of light and dark on a screen behind the slits. People have 'proven' that light is one or the other, but the truth is in between. You might think of a photon as a little packet of waves, as if you took a long rope or hose and sent a burst of waves down it.
Light is more commonly known as photons in particle physics. Photons sometimes act like billiard balls, meaning they come into contact with matter and reflect, deflect, absorb, or refract off of it. On the other hand, photons sometimes act like waves and interfere with one another and themselves in such a way that only waves could be the possible answer for their actions.

I want to make sure that it is understood that not only does the photon itself act like a ball, it also itself acts like a wave - all by itself. No matter what experiment you do, either the photons will act like billiard balls, or will act like waves.
It's called the "wave/particle duality" of the nature of light (and all other forms of

electromagnetic radiation too).

It means that if you set up an experiment to detect and measure the behavior of waves,

you find that light has it. And then, if you set up a different experiment to detect and measure

the behavior of particles, you find that light has plenty of that too. Whichever kind of behavior

you're looking for, light has it.

Answer 2

1. Light behaves as a wave when it undergoes interference and diffraction, where it shows properties like wavelength and frequency.
2. Light also behaves as a particle known as a photon when it interacts with matter, as seen in the photoelectric effect where photons transfer their energy to electrons, causing the emission of electrons from a material.

Answer 3

If you are referring to the wave-particle duality of light, it is a theory Albert Einstein came up with. The way light acted really confused scientists. Light sometimes acts like a wave, and sometimes acts like a bunch of particles. Albert Einstein ran a multitude of tests. After all of his tests he came to the conclusion that light is unique in that sometimes it can act like a wave, and sometimes it can act like particles.

Answer 4

Light is electromagnetic radiation. It's a moving electric field that is propagated simultaneously with a moving magnetic field each set at right angles to the other. Light's standard unit of issue is the photon. Light has wave-particle duality, and that is its nature. The properties it exhibits, its behavior in a given situation, may be that of a particle or that of a wave, depending on the circumstances under which light is observed. Light will not be pinned down more than that. Is it a wave? Is it a particle? It's a wavicle. Get used to it. And hit the links for more info.

Answer 5

Nature of light : Light has wave-particle duality . If you didn't understand this answer you may move to another similiar question such as : what is the precise nature of light ? you'll get what you need. :)

Answer 6

Light is composed of photons of different wavelengths. Photons are massless particles or packets of energy. All photons travel at the speed of light, 3.0 x 108m/s.

Light is an electromagnetic wave.

Light is light. We have several models to explain the behavior of light, the photon and the wave model are two of them.

Answer 7

The nature of light depends upon how you are observing it. Light has what is known as wave-particle duality. That is to say, it shows both the characteristics of a wave (for more information look up the Young's slits experiment on Google), and of a particle or "packet" of light known as a photon. So the nature of light is either a particle or a wave, but it depends on the method which you use to observe the light. Which begs the unanswerable question: What is light when you aren't observing it :-)

Answer 8

That means that light sometimes behaves as a stream of particles, and sometimes as a wave. It really depends what experiment is done on the light. The same can be said of different elementary particles, such as electrons - they are usually considered "particles", but in certain experiments, they, too, manifest a wave nature. For more details, read the Wikipedia article on "wave-particle duality" (or some other source of information).

Answer 9

Light acts like both a particle and a wave.

Answer 10

Light has two natures that can be thought of as both a wave and a particle.
