Sorry! That post should have been directed to Silversoul!

Oh no sweat, I kind of figured that after I posted.

I have another reply to Silversoul, I dont think science proves anything beyond a doubt! Doubt is a key ingredient in science (of course in many things doubt is relegated to an enormously small percentage, yet still exists).

Apparently spelling isn't either. :wink:




Heh, I would go so far as to claim that my abilities at spelling are a learning disability.  I do a fairly good job of working with it, but no, spelling and I do not get along, at all.  I use a very limited vocabulary when writing, compared to speaking, as I don't know how to spell most words correctly.

So is light just energy like heat?

Is heat a wave?

Now I'm really :confused:

Light is one form of energy, yes. The thing most commonly referred to thing as "heat" - that feeling you get when you put your hand up beside a hot oven window - is a type of light, infrared light.

Of course there is another type of "hot" to talk about, and that is the "thermal vibrations" that molecules undergo (at all but absolute zero).

I think that experiment proves that a photon of light is neither a particle or a wave...not that it is "both".

Light behaves like a wave or particle...but experiments such as the double slit prove light is, in fact, something more.



I was wondering: Isn't the same true of electrons? I think I remember hearing that somewhere. What about protons and neutrons? Are they just particles, or are they something more as well? Is there anything that is "just" a particle?

No, there is nothing in the atomic world that is shaped as a "particle" (as they are most often understood to be). A particle is a hundred year old explanation for the atomic world.

Well, I think dont think the particle description of matter is completely antiquated idea. It has particle/wave duality, just like light does.

Silversoul-> Yes the same is true of electrons, protons, anything we consider 'matter'. When light which was believed to be a wave was found to have particle wave duality a French nobleman/scientist, deBroglie, postulated that perhaps matter, which is believed to be a particle also has particle/wave duality. He ran some numebrs and found the wavelength of particles. Now electrons can be run through the double slit experiment just like light, and they show the same properties. That is if you send one electron through the slits it will interfere with itself and create a interference pattern. That means the electron must have went through both slits, thus it must be a wave. But when the electron strikes a surface it only creates one little mark, so it must be a particle. (Note that if you observe the particle to see which slit it goes through, you get no interference pattern) Thats probably a little over your head, do some searching on particle/wave duality, double slit experiment, and deBroglie wavelength if interested.

Entire atoms and even molecules can be shot through the double slit and they also have dual personalities. The bigger the thing, the more it behaves like a classical particle and the less it behaves like a wave.

That's why I behave almost entirely like a particle: cuz I'm BIG! :tongue:

According to one of my texts, they have gotten an interference pattern off of a bucky ball (C-60)!

The coolest aspect of light... It travels the same speed no matter how fast you are going, or the source of it is going. No matter how fast you go you always measure a light beam traveling at the same speed.




So what happens if I'm driving my car in space at the speed of light and I turn on the head lights?

We can never know 100% of any properties of these quanta. We can only theorize, and model the system on the evidence we have.

The most useful model for 'light' as electromagnetic radiation, is that it is a photon, with a finite ammount of energy, which is proportional to its wavelength. It has a magnetic wave component, and an electrical wave component, which are 90 degrees out of phase.
