Enlighten us, O Guru! |
I didn't say that all waves travel at the same speed. |
But you said there's a one-to-one correspondence between frequency and wavelength*. This can only be true if velocity is invariant.
* As I'm in a charitable mood, i'm going to disregard "frequency=wavelength" and just put it on the Big List Of Unbelievably Stupid Things Which Joe Is Too Pig-Headed To Retract. |
There is a one-to-one correspondence between frequency and wavelength in any given context. |
Ah, but that's not what you said is it Joe?
You said
wavelength = frequency
You didn't say
wavelength = frequency when everything else is constant (it's still not true because 520 nanometers doesn't equal 3.5 gigahertz anyway).
I'm pretty sure we have screenshots.
Here's a hint: The equal sign "=" does not mean 1:1 correspondence. As you have been told many times and ignored.
Keep digging this is almost as good as the hail/water and a baseball can't be the same size as a rock because of density thing. |
When I turn the frequency knob of a signal generator it changes the wavelength. That is all it changes.
By your logic the manufacturer doesn't know what it is doing. |
You've moved the goal posts again.
You didn't say "for EM radiation at a constant velocity; wavelength = frequency"
You said "wavelength = frequency" (still not correct because the equal sign doesn't mean 1:1 correspondence)
You have all but admitted that the thing you actually said isn't true.
Now, if we only convince you that length isn't the same as time... you'll be as knowledgeable as most 2nd graders. |
Kevin, You were NEVER part of the discussion so you don't know what I was saying. |
But I was. So, please tell us about the discussion. And the context.
If you are having a hard time remembering, let me remind you. You claimed:
Frequency = wavelength.
No additional context. No qualifiers. No "everything else being equal". No "with constant wave velocity". No "in a single medium". No "only on Tuesdays".
Simply:
Frequency = wavelength. |
You are lying, as usual. |
Nice try Joe. Unfortunately the evidence does not support this claim. You clearly stated that wavelength = frequency without any qualifications.
