Question

If a quantity is quantized, that means:
a) It can only take real values (no imaginary or complex values allowed)
b) The square of its modulus can only take real values
c) It can only take values that are related to integer multiples of something

Answer 1

I'd not choose "c", but I can't decide between the other two.

Answer 2

c

Answer 3

Why?

Answer 4

Goes down to the core of "quantum" mechanics. Think about planck's constant, and such.

Answer 5

ask why a) might be the answer, maybe?

Answer 6

What, it's "c" because quantum means discrete?

Answer 7

Discrete means countable sets, and that means integers.

Answer 8

yep!!

for me, at least!!

Answer 9

@inkyvoyd Is that what you think too?

Answer 10

I don't see how planck's constant applies.

Answer 11

Well again, that is the whole point of the word "quantum" in "quantum mechanics". questions similar to this one might help. http://physics.stackexchange.com/questions/32112/classical-limit-of-quantum-mechanics

The whole reason we got quantum mechanics in the first place was because people were working on problems, using a finite h planck's constant, and letting it approach zero. But shocking was that you couldn't get correct results when you let h approach zero... it stayed as a small, but finite, QUANTUM number.

Answer 12

So it's definitely not multiple answers?

Answer 13

Figure that out for yourself

Answer 14

Aw, I've been doing this assignment all day. (I don't have any more time to explore the book.)

Answer 15

all those answers are correct

the book wants the last answer though

Answer 16

Thank you very much!
