Then where does dark matter and dark energy come into the picture?ZapperZ said:NO there isn’t!

Ok, but it tells something about how these phenomenas are operating. So they all have something in common?Nugatory said:“Hz” is just a convenient way of saying “per second”, telling us nothing about what is happening that many times per second.

How 'phenomenas' travel thru the universe, and how beings percepts these observable happeningsweirdoguy said:What does it have to do with electromagnetic waves and your initial question?
Ok ESL, pardon my english. I am norwegian. I meant that they are operating in a vibration kind of behaviourDennisN said:(my bolding)
Not really. Hz is a unit and says nothing (or very little) about the process itself, other than that there is some sort of repetition going on in the process.
Compare with a watch and the unit second (s). The unit "second" says nothing about how the watch works, other than it (the watch) measures time.
Both sound and light are wave phenomenon (in classical physics), and they are two phenomenon which often have frequencies associated with them. But the two different phenomenon work very differently. Very differently.itallcomestoenergy said:I meant that they are operating in a vibration kind of behaviour
itallcomestoenergy said:Then where does dark matter and dark energy come into the picture?
Light waves and sound waves are different things and no, sound waves don't necessarily operate at lower frequency; there is overlap.itallcomestoenergy said:Okey, so the medium is vacuum. With hints of atoms(?) What about sound waves? They operate in a lower frequency, but they are not transferrible in vacuum? Do I get this right? The reason I ask is because of illustrations of lights frequency spectrum.
Yes, they all have a frequency. That does not mean that they are all vibrations. Not all things that have mass are bananas, just like not all things that have frequency are vibrations.itallcomestoenergy said:Ok, but it tells something about how these phenomenas are operating.

lol. Good point. But if it is frequency that describes that vibration is common. Isnt it this we should 'science' more? Thinking of how energy works?Dale said:Yes, they all have a frequency.

Yes, I am sound engineer so I am aware of that :)russ_watters said:Light waves and sound waves are different things and no, sound waves don't necessarily operate at lower frequency; there is overlap.
Yes, but it can be affected by vibrations, and there on Hz(?)DennisN said:Both sound and light are wave phenomenon (in classical physics), and they are two phenomenon which often have frequencies associated with them. But the two different phenomenon work very differently. Very differently.
And here's a trick question for you regarding Hz:
A wheel that is spinning with a constant velocity performs a repeating behavior, where the wheel spinning around a centre can be expressed in Hz (revolutions/second). Is this a form of "vibration"?
EDIT: Also, computer processors have different frequency values associated with them (kHz, MHz, GHz etc), but is this a form of "vibration"?
itallcomestoenergy said:if it is frequency that describes that vibration is common
Than why can we describe Hz in different phenomenas, where is the connection between these phenomenas?weirdoguy said:What? I'm not even sure what you are trying to say. Frequency is one of the many characteristics of vibrations and waves, it does not "describe that vibration is common".
itallcomestoenergy said:Than why can we describe Hz in different phenomenas, where is the connection between these phenomenas?
ZapperZ said:We can describe that it as having a frequency of 20 Hz.
weirdoguy said:1Hz
Vibrating is something that operates as a wave. The simplest form of wave is a sine(?)ZapperZ said:A object makes 20 complete revolution in a circular motion path in 20 seconds. We can describe that it as having a frequency of 1 Hz.
So, I used the same units here, i.e. Hz. Tell me what's "vibrating".

itallcomestoenergy said:Vibrating is something that operates as a wave. The simplest form of wave is a sine(?)
Im sorry. Phenomenas operating as a wave affects everything around it. So the vibration in this particular example, comes also from it surroundings. Thereby might particles vibrate. For example phonons.ZapperZ said:You did not reply to my question, but instead, you went off on your own tangent.
I brought up something that can be described in terms of the unit "Hz". You claim that everything using that unit must be a vibration. I asked you to tell me what is "vibrating" in that example that I gave. Please answer that.

It was an example, just as you had one example. I have no answer. YetZapperZ said:Not only is this puzzling, but it is also nonsensical.
There are no phonons here.
So one last time before I stop playing this game, what is vibrating in my example?
Zz.

ZapperZ said:It was an example of what, your inability to comprehend the scenario?
Zz.
itallcomestoenergy said:Okey, so the medium is vacuum.
What about sound waves? They operate in a lower frequency,
Yes, and the medium is particles in the air, water or more solid matter.Mister T said:No. There is no medium.
No. Sound waves are vibrations of a medium.
Not all waves are vibrations and not all vibrations are waves. They are two different things that you are trying to mix up here.itallcomestoenergy said:Vibrating is something that operates as a wave. The simplest form of wave is a sine(?)
