Joule Thief 101

[MileHigh]

One more time Brad that's mostly useless trash talk.

Bradley doesn't like his dose of cod liver oil but Bradley does like his serving of ice cream after school.

You should try writing that out in long-hand 500 times just like back in elementary school.

You have never tried to answer the two questions in your own words.  If you truly understand resonance then you should be able to answer the questions in simple terms with no problems.  If you can't do that then the thread should be handed over to Magluvin.  I will give my answers in April.

ok MH, your turn

tell us the mechanics behind the resonance of the wine glass

i'll hold my breath

please feel free to omit any

...technical word salad

[sm0ky2]

"the wine glass resonates because you are tapping it"

is that the answer?

just because there is no "air" present to vibrate your ears, does not mean the waveform completely ceases to exist.
soundwaves can travel through space with no medium, and manifest themselves on the other side back into a medium, where they can then again be heard by your mortal sensory appendages.
is it technically "sound"? that depends on how you choose to define what "sound" is.....
and also to some degree, your ability to evacuate your test chamber.
all this is irrelevant to the discussion.
and is just a subservient attempt to distract everyone from your idiocracy.

Your allusion to the irrelevance of a resonant chamber, with respect to something that resonates...
is quite absurd.

without such resonant chamber, the glass would NOT resonate.
it would behave much like the flat piece of glass and just go thunk,.
(actually the flat glass does resonate, just not for very long and the wavelength is much shorter)

   

[sm0ky2]

if you break your wine glass and pick up a piece of the "glass itself"
and flick it

f = [sqrt(E/4L^2p)]

where E is Young's Modulus at that temperature.
L is the thickness of the glass
p is its' density


^^ there that's four sentences.
unfortunately, your wine glass is not only SiO2, there are other components in the glass material.
which makes the reality a more complex equation.

 mortal sensory appendages ??

surely you jest ....

his holiness has no such appendage !!

And if he did surely he would not waste it in such a fashion ...as listening .

please do not confuse him with the facts ,his mind is made up ...

                                         April [would that be April 1st??]
so let it be written so let it be done.!
