Light is in form of either Wave lengths or Particles ?

Question

Particles, would you please expain Light in terms of particles? Give examples?

Thank you.

Answer 1

Photons has mass, and can combine with electrons to form an electron with higher mass and energy and thus rising from its orbit to a higher orbit,
the reverse is also true; an electron can emit a photon and loose mass and energy, and consequently drop to a lower orbit in the atom or molecule where it belongs,
we know fore sure that photons are matter that has mass and energy, the relation is E=mc2 (C to the power 2), where E is the energy of the photon, m is its mass, and c is the speed of light

But it behaves in a strange way as waves
the relation is:
E=hv, where E is the energy of the photon, h is planks constant, and v is the frequency of the photon

we can see that light is actually matter that reach the eye and react to give a special signal to the brain as to which colour it is

Answer 2

I once heard light neatly summarised as follows, "it travels as a wave but arrives as a particle". Whether we perceive light as a particle depends on how we choose to look for it. If you set up an experiment to detect light as a wave thats what you'll see. If you set up to look for particles then you'll find particles. Things get really bizarre when you fire a single photon at two holes. Logic says it must go through one or the other hole, but in reality it goes through both - at the same time ! Thats why no-one can really say exactly what a photon (or any other quanta for that matter) really "is".

Answer 3

this question has no meaning in physics, all things (not only light) has a particle or wave form depending on what you want to know , in the case of light you have rhe particle view (photons) or the wave view (classical physics) and both are consistent with the theory and with each other if they are not used at the same time...

Answer 4

In classical physics light is generally regarded as a wave however in quantum physics it can be a particle. As electrons lose energy they can drop to a lower energy level which will emit energy as a photon - which is a particle. Lasers use this theory however many great physicists didn't believe in quantum physics as it mostly cannot be explained.

Answer 5

The photoelectric effect is explainable by assuming light is particular in form.

When the particles have a certain energy they are absorbed and the absorbing electron is propelled to a higher energy position.

When the electron returns to a lower energy level a photon is emitted.

Answer 6

The momentum transferred by utilising utilising bouncing a photon off some ingredient ( or having it absorbed) is larger if the frequency is larger. Your common waves are quite some photons and the aptitude indoors the wave is proportional to the aptitude in a guy or woman photon* this kind of photons consistent with 2d you're pumping out, so in terms of capacity transferred that's not considerable what the wavelength (frequency) is distinctive than in terms of the overall performance of generating, guiding and reflecting/absorbing the photons (for an identical capacity (or intensity) you're able to desire to apply quite some low capacity photons or fewer, severe capacity protons). maximum proper of success

Answer 7

Photon: Particle of light.

Answer 8

Light is formed of photons, but they have zero rest mass, otherwise it would not be possible for them to travel at the speed of light! However, you will never observe a stationery photon. They appear to have mass, though, by virtue of the energy they carry, according to Einstein's equation E=mc^2, and their frequency is related to their energy by E=hf, where h is Planck's constant. The wavelength, of course, is c/f.

Answer 9

Light is actually the absence of subatomic particles called darkons. For example, when you flip a light switch it disrupts the flow of darkons and the room becomes light.

Answer 10

Light Wave, it does have a mass though, or so I have been told, must be very light though other wise it would take infinite energy to travel at the speed of light???
