Light's Observed Wave Nature:

- Diffraction (bending around corners)
- Interference
- Polarization
- Reflection and Refraction

Light's Observed Particle Nature

- Photoeletric Effect
- Compton Effect

Those are some phenomena that can be observed regarding light's wave-particle duality. Light behaves as a wave, when you allow it to propagate in a situation where you are expected to see wave properties. For example diffraction. Take a flashlight and shine it onto your finger. Look at your finger's shadow. If light is not a wave, then the shadow should have a perfect contrast between the dark area, the shadow, and the area that is lit by the flashlight. However, this is not what happens. You can see your finger's shadow a little vary in contrast on the edges going to the center of the shadow with the center being the darkest.

For the particle nature of light, it is a little tricky because you can not observed this in day to day life. You need some equipent. Which is why the wave nature of light was first acknowledged. For more information on the wave and particle properties of light, you can google the property or go directly to wikepedia.

ok. but if both experiments are carried out, wouldn't that result to: light as both wave and particle at the same time?

That has never happened. When you design and experiment, there are two possibilities. Either your experiment, will show the wave nature of light or the particle nature. If, however you can design an experiment that shows the duality, then that will be a major breakthrough possibly Nobel worthy. hehe! Usually, when you design experiments that observe light at a very very small scale, its particle nature tends to be dominant. There are so many things involved. It will lead you to Quantum Theory theory of light or Quantum Electrodynamics.

ok. thanks, mr.fritzd.

if light is energy and energy has mass, then does it mean that light has mass? if if passes through a gravitational field, will it have weight and consequently be bent? if that is the case, then the light we receive from distant stars would not be from its exact position right?

from what iv understood, light doesnt have any mass. not all particles that has energy has mass. gluons are aslo massless. []Error

light bends around a massive object or with a strong gravity because it is travelling thru a bent spacetime [due to gravity and mass]. since gravity as described by GTR [general theory of relativity] is just warped or dent spacetime.

i have a question: is E=mc2 the way for the virtual world to materialize?

What do you exactly mean by Virtual World Materializing? Sounds more like sci-fi than scientific. hehehe I'm both accustomed to sci-fi and pure scientific. hahaha.. E=mc^2 is just a simple equation that tells us that matter and energy are in fact the same. It also tells us that energy can become matter and vice versa. It also tells us that some time ago during the beginning of the universe, it is possible that everything was pure energy. Another thing about that equation, it is not the full form of the equation. Einstein just gave that equation to make things easier to explain to non-physicists. The full equation contains the relative mass which is related to the motion of the particle. I won't explain further kay basin ato i-derive ang equation. It's not really too difficult to derive the equation from a Physicist's point of view. Dili gyud highly advanced ang mathematics involved not like General Relativity nga bisag unsaon lisod gyud kau. hehe =)

You can easily tell from the posts, who are sincere and eager in sharing the facts (and trying their best to make them be understood in layman's terms), and those who are posers and just people who have nothing to do and just want to juggle around scientific terms to sound "smart" and learned.

Kudos to the true seekers of knowledge. To those who are here just to mess around with this subforum, beware my wrath.

very interesting posts, sir fritzd. i first heard of quantum theory in one movie where the einstein character demonstrated it to a child with a water fountain, sunlight and his finger. i must admit though na makanosebleed jud ni na stuff.

but anyways, up for this one

the virtual world i mean here is the metaphysical world [ambot lng kaha anang simulated reality thru computer]. its different from the virtual particles in physics only because the metaphysical world is made up of complex stuff. virtual particles are just particles, the metaphysical are like the biological stuff. we dont see this metaphysical stuff since it is decohered from our vision. much like a radio with a stuck tuner. it can only tune in to a single broadcast. the other stations cant be heard. if this metaphysical stuff exists, since theyre just pure energy then by E=mc2 they will materialize [by tuning to the right station]- they will acquire mass and would exist in the physical reality.

naa ko link na mo explain nga dli lng physical reality ang naa. iya gani theory of everyting [TOE] ky dli equation nga mo unify sa four fundamental forces kng dli unification sa physics, metaphysics ug consciousness. physicist ni cya nga mo tuo ug astral projection thru meditation.

ohh.. ok... i see what you mean. unfortunately, from what i know, the answer is no.... E=mc^2 is not the answer to what you are talking about. What you are talking about is more on philosophical abstractions of reality. They are trying to explain the philosophy of existence using ideas in Physics because in fact Physics is the result of Philosophy and Mathematics. I've seen and read many articles about this but as of now its mostly theoretical in nature. I don't know much about it. It is a very interesting field. But as of now its all just theory. I'd have to say String Theory is at a better position than this. I have a friend here who is also a physicist (actually my roommate last semester, haha). We always talk about these things. The meaning of existence, and consciousness through Physics.

If you think about it critically, the universe we have right now is a product of all physical theories and fundamental constants. You can also ask why does the universe operate in the way it is now when it shouldn't have to. You can also ask the question, "Why does gravity follow the inverse square law?" Physicists have have done simulations using astronomical objects using an inverse cube relationship instead and they found out that the planets simply can not hold on a stable orbit. And the universe wouldn't exist at all. It is like our universe was a grand design by a higher being way beyond our comprehension of reality. We see reality now based on our past observations and experiences. A higher plane of existence existing out there is simply just way beyond our futile minds. I agree, it is possible that our universe could be just a virtual world masterfully design but virtual in an abstract way. For us it seems real.

Anyway, I'll stop talking. There is really no right answer for this one. It's very difficult to prove. It's like searching for God through science. Einstein said that, "God does not play dice with the Universe." It's a short and simple sentence which has wild implications. And I agree with Einstein, the universe is masterfully design by a higher being who we probably call God. Anyway, sorry for straying away from the topic. hehehe!
