Now, if I only knew what a "Compton wavelength" is, I'd be all set .... I guess looking that up is a reasonable exercise for the student.

How are the Compton and de Broglie wavelengths related?

Day one of quantum class from hell: "The wavefunction contains all knowable information about the system. Extracting it is an exercise left to the student. Good day."

I'll defer to "Physicist" on this; he's the one who brought it up!

Thanks, great article and what a shame these guys split 94,000.00 amd a jock who can't read makes millions, the dummin down of America!

The dumb jock who can't read is nevertheless smart enough to produce something that has at least SOME effect on the life of ordinary people.

Occasionally an engineer gets lucky enough to do this, then he makes those dumb jocks look like paupers by comparison. (Bill Gates).

I think you meant DeBroglie wavelength

Compton wavelength = h/mo*c

DeBroglie wavelength = h/p
momentum = p = sqrt(2*mo*v)

The DeBroglie wavelength is like a modulation on the compton carrier.

And the compton carrier rules come to us from the FCC.

ooops!

P=mo*v
v = velocity

post #25 had kinetic E as v.

Remember the old bumpersticker "Honk if you passed P. Chem." :)

Pass it? Heck, I taught it! (smile) I do have a copy of that sticker in my office.

If my old prof. explained one more variation of the Ideal gas law, I think I might have strangled him. :)

Ach, they're all the same. It's just a matter of what state variables are constant. I didn't even bother with Boyle's, Charles', Guy-Lussac's, etc.'s Laws.
