Joule Thief 101

How does a wine glass resonate, what is the mechanism?

Resonance in a wine glass ,is the wine glass vibrating at it's natural resonant frequency

By receiving pulses of energy at the correct !time!<--time MH) at it's natural resonant frequency.
These pulses of energy can be either pressure waves,or physical contact taps on the glass it self.When enough energy is stored in the glass,and the molecules of the glass are agitated,the glass then go's into resonance.
Whats your point?.

How is the resonant frequency of a wine glass determined?

Of what?
Mechanical,acoustic,or electrical resonance?
And you say i am no good at explaining things.

If you are referring to a wine glass,then there are a multitude of things that will determine the resonant frequency of that wine glass--there is no one simple MH equation that can be used to calculate that resonant frequency.

Can you list all those things that will determine the resonant frequency of a wine glass MH ?--no chance in hell. You are full of it. You ask questions you your self cannot even answer.
What grade of crystal is the wine glass made of MH ?.
What are the specifications on the physical size and parameters of the glass?.
How long is a piece of string?.

i am surprised it would take you so long to carry out the research needed by your self to put the answers together.

I am giving you four to eight weeks to see if you can actually understand what resonance is and figure out how a wine glass resonates.

How does a wine glass resonate, what is the mechanism?

Answer-By receiving pulses of energy(from a prime mover) at the correct !time!<--time MH) at it's natural resonant frequency.These pulses of energy can be either pressure waves,or physical contact taps on the glass it self.
Quote physicsclassroom.com -resonance - when one object vibrating at the same natural frequency of a second object forces that second object into vibrational motion.

Answer correct.

What is resonance in a wine glass

Answer-Resonance in a wine glass ,is the wine glass vibrating at it's natural resonant frequency
Quote hyperphysics :a resonant frequency is a natural frequency of vibration .

How is the resonant frequency of a wine glass determined?

Answer-If you are referring to a wine glass,then there are a multitude of things that will determine the resonant frequency of that wine glass--there is no one simple MH equation that can be used to calculate that resonant frequency.
What are the specifications on the physical size and parameters of the glass?.
Quote Physicsclassroom.com- A resonant frequency is a natural frequency of vibration determined by the physical parameters of the vibrating object.
My questions regarding the physical parameters of the wine glass were legitimate and correct.

You are a joke MH--that much is clear.
You cannot ,have not,and will not answer your own questions-that much is also clear.

Anyway,you enjoy your self over there in wonderland.
It's been a hoot

Well the problem is that even if the "missing" physical size and parameters of the glass were given to you, you still wouldn't be able to answer the question.  Are you bluffing?  Go ahead and fill in your own parameters and answer then.  I said the same thing to you about the Joule Thief when you asked for specifics and you ran away.  Will you run away again?

I will take this one step further because it's annoying.

Why did I put "missing" in quotations?

Let's look at the question again:

How is the resonant frequency of a wine glass determined?

Is that question asking you for specific values?  The answer no.  Now can you understand the question?

Here is an analogy to show you how ridiculous your balking is:

Supposing you are in grade 6 and the teacher says to the class,  "Write up a short story describing how you fill up your car with gas at a gas station."  It's a test for the children in grade 6 to see if they are capable of describing something in a logical order and to see if they can put sentences together properly.  It's not a skill-testing question to see if they know how to pump gas.

Now if a student complains that he can't write the short story because, 1) the make and model of the car is not defined, 2) how empty the gas tank is is not defined, 3) the type of gas is not defined, and 4) the brand of the gas station is not defined, then clearly there is a problem with that student.

That's exactly what you are doing when I ask you how the resonant frequency of a wine glass is determined and it's ridiculous.  The question can be answered without specifics.

So you can answer the question by filling in the "missing" physical parameters by yourself, or you can answer the question as it was posed to you just like the kids in the class can write the short story about how to pump gas without specifics.

I will return to this subject in four to eight weeks if you can't answer the questions.  Simple, basic questions can be answered with simple, basic answers.

Forget it Webby, the questions about the wine glass resonance are 100% legit.
