Up until the late 1800's the wave picture of light was the prevalent theory, as it could explain most of the experiments done on light. However, there were a few notable exceptions. One such exception was that associated with blackbody radiation, which is the characteristic radiation that a body emits when heated. It was known that this radiation changes in nature as the temperature changes, and experiments on ``blackbodies'' (perfect absorbers and emitters) show the following typical curves of the intensity of the radiation (energy emitted per unit time per unit area) vs. the wavelength at a fixed temperature T.

When the wave picture of light was applied to this problem, however, it failed - it predicted that the intensity, I , for a given temperature should behave as

which agrees with the experimental data for long wavelengths but diverges for short wavelengths, unlike what really happens.

In 1900 Planck devised a theory of blackbody radiation which gave good agreement for all wavelengths. In this theory the molecules of a body cannot have arbitrary energies but instead are quantized - the energies can only have discrete values. The magnitude of these energies is given by the formula where n = 0,1,2,... is an integer, f is the frequency of vibration of the molecule, and h is a constant, now called Planck's constant:

Heck... everybody knows THAT

>>>IF YOU GUYS DON'T WAKE UP, I'M GOING BACK TO MY FISHING FORUM!!!!!!!!<<<

YEAH WHAT HE SAID. I'M GOING BACK TO MY DOMINATRIX MIDGETS FORUM!!!!!!!

did I say that out loud?

[r-q-tek86]

I did the dominatrix midget thing once... but getting my calves whipped didn't do much for me.

[fredhead]

I have complete Grand Funk Railroad, complete Led Zeppelin (except the remixed box set) and complete Ronnie Van Zant Lynyrd Skynyrd collections.

A little bit of everything from Aerosmith th ZZ Top.

Rock, Blues, Country, Classical, Jazz, even steel drum and bagpipes.

[HOTTIEBOY]

No, its not midget whipping. Its MIDGET WHIPPING.

Whipping people with midgets.

[fredhead]

They're not midgets....they're vertically challenged.

[fredhead]

Follow, follow, follow, follow,
Follow the yellow brick road.

Old bumper sticker I have stuck up in my garage:

Auntie Em, Hate you , hate Kansas, taking the dog. - Dorothy

[r-q-tek86]

Is that like Cool Whip?

I was a series Zephead in college, but kinda burned out on it. I started getting into some wierd music as I started producing videos (looking for background music). There is a new radio station here that plays all sorts of stuff and is starting to draw me back to some of the old stuff that I simply burned out on several years ago, like:

Rush
Black Sabbath
Pink Floyd
Zeppelin
Steve Miller
(old) ZZ Top

[r-q-tek86]

71?

[fredhead]

What? No Zappa?

I used to have about 25 of his recordings. Mostly on cassettes. I got burned out on him, and the tapes wore out.

"I have to have a raise," the man said to his boss. "There are three other companies after me."

"Is that so?" asked the manager. "What other companies are after you?"

"The electric company, the telephone company, and the gas company."

[r-q-tek86]

I was never big into Zappa... I know, I know... sacrilege.

[Millee]

LOL!!!

[groovejedi]

I as on a long lunch, thanks for the smiles. I got an interview today after work, back into architecture. yeah!

[fredhead]

Speaking of fishing, we brought home 24 good sized fish Sunday from 2 hours of fishing. We were cleaning fish until after 7:00 PM.

But nothing like good fresh fish.

[fredhead]

You ever see this album cover?

[fredhead]

Try again...

[r-q-tek86]

I got an interview today after work

Sweet! Good luck!
