I know this is from last years syllabus, but its in my portfolio,
which its due 2morrow Can neone help plz??

(i) Identify the main ways in which de Broglie's matter waves differ from Maxwell's electromagnetic waves.

And....

(ii) If you were asked: What is it that is vibrating in a de Broglie wave, what answer would you give. Why?

Any thoughts?

just thought Id reply since u were complaining abt it in the other thread....but I cant help u on ur Q's

 

[-X-]

Sorry cant help either but is this quanta to quarks topic?

 

[Chand]

looks like it, but like he said, its last yrs syllabus, so im guessing its not on this yrs...

edit: actually in another thread someone said its from I2I..so not sure..

its not Q2Q, its from the old syllabus.
it is ideas to implementation

de broglie's waves were standing waves, where it was proposed that electron move in a wave like manner around the energy level [imagine a sine wave bent around in a circle. there fore the electrons moved in his matter waves]

and as for maxwell, we all know that he proposed the idea that electromagnetic waves were fluctuations of electric and magnetic waves.

now why we are doing this????

dont ask me, the teacher is a dumbass

Hmm... I'll have a late crack in addition...

i) deBroglie's matter waves exist in all matter; the wavelength of which is related inversely to mass and velocity, in contrast to electromagnetic waves, which varies inversely with energy (there is room for a parallelism here).

ii) Why, in a sense, matter itself 'vibrates', since the wave-particle duality applies to all matter. If asked, what vibrates in a single quantum of 'light', what would you answer? Exactly the same.

There, absolute nonsense.

Ahhhhh crap... Luv to have known this yesterday

But its ok, I got the answer...

Thanx for the help!

Hmmmm.... wherez the time machine at???
