Question

Is all forms of energy quantized or only electromagnetic ?

Answer 1

quantisized

Answer 2

i spelled wrong. Quantized

Answer 3

here this should be helpful http://www.kentchemistry.com/links/AtomicStructure/PlanckQuantized.htm

Answer 4

My textbook says that the light energy is quantized and can exist only in multiples of \(hf\). Where \(h\) is planck constant and \(f\) is the frequency of light. I'm wondering what are the implications of this to other forms of energy...

Answer 6

that staircase is an interesting analogy of quantization, thank you for sharing @habbababba1

Answer 7

anytime man

Answer 8

r u hindu?

Answer 9

Yes

Answer 10

i thought so i am too

Answer 11

oh well have a nice day

Answer 12

@Qwertty123 nonconstant light velocity is a crazy concept ! I think we may need to throw away most of our science if the speed of light in vacuum is not constant hmm.

For now, I'm more interested in quantization of energy. Lets look at speed of light some other time may be :)

Answer 13

okay :)

Answer 14

I agree with you BTW! Some of this Science stuff is crazy..

Answer 15

i was thinking about all this, in a vague half baked way...
calculus is so effective in dealing with natural phenomenon because we observe them to continuous, like the motion of planets, work done etc etc

so if everything is quantized, what are the implications?.. that calculus is not the appropriate tool?

Answer 16

observe them to be*

Answer 17

Haha ofcourse! when somebody says that you're a wave, you must think he is crazy!

I don't think QM says that space is quantized though...

Answer 18

From this it says http://www.livescience.com/33816-quantum-mechanics-explanation.html

Answer 19

Oh if all of forms of energy is quantized then the heat energy and its measure temperature is also quantized and calculus should fail ?

Answer 20

Great question! Let me think here..

Answer 21

no

Answer 22

What do you mean by energy is quantised? Light is quantised in the sense every light beam of frequency \(f\) is carried by photons of energy \(E=hf\) but the frequency \(f\) is continuous and I think all frequencies can be generated via appropriate means.

Answer 23

That is an interesting point. Since the frequency is continuous, we can get any arbitrary value for the photon energy by choosing the appropriate frequency hmm

Answer 24

Yes you can. Black-body radiation generates a continuous spectrum. It is only that the energy of light comes in quanta, not that we can only have quantised amounts of energy.
