Frequency of pitch in a cup of tea?

I guess that where you tap the cup is important. The ringing sound will be generated by the energy you put in from the tap. The tone is dependent on the internal volume at the point where you tap, and the thickness of the cup where you are tapping.\n\nIf it were a cylinder I guess that it would produce an even tone all over, maybe you should try that?\n\nFar from being boring this is an interesting question about harmonics, I am off to the kitchen, with a spoon...

Try the sonometer or the resonance experiment

ok. here is one "HYPOTHESIS OF SOUND"!\n\nLet me know if you want another one! I got plenty.\n\nlol

The frequency of the sound wave determines the pitch.  When you speed up a recording, you are increasing the frequencey, so pitch rises.  The reverse happens when you slow down a recording.

there are many factors to be considered and nature isn't really a controlled environment, if wind changes speed then it will be higher or lower pitched. Pitch is the way we percieve sound and it is directly related to fequency ( higher frequency, higher pitch), frequency is wavelenght times speed so if your waterdrop falls just a little faster or the wind speeds up you wouldn't have a consistent pitch. Furthermore, if you did have such a controlled environment as in the description of your question where "tapping a certain weight stone or mineral to produce a pitch or tone that is always the same" or "a certain branch from a tree when hollowed and blown across a hole like a flute" those things will have a certain pitch, but that is no longer m=nature, the variable of mankind has come into play

Yes, frequency changes, the easiest what the think of it is with a guitar, if you pluck a guitar string without pressing on it, you have a low frequency pitch, placing your finger an one spot (making a shorter wire) and plucking and the same spot as the first time, with the same force gives you a higher pitch (faster frequency), and you must have constant position and force (amplitude, since the amount of initial force give you the amount of string that is initialy lifted, which would be the amplitude of the pitch) for it to be a valid experiment, and of course using the same thickness of wire, since the thicker the wire the lower the frequency for any constant amplitude

A tea kettle makes noise because of the air inside of the kettle expanding due to the increased heat.  Most of this heat comes from the water's increasing temperature, since the water is closer to the heat source than the air.\n\nWater reaches boiling point at 100º Celcius.  Water does not instantaneously go from liquid to gas though.  It requires a good deal of energy before it goes from a liquid to a gasous state, more energy even than raising it's temperature from room temperature to 100º C.  While this energy is building up, the temperature of the water is not rising, the molecules are merely breaking apart from each other.  Since the temperature is not rising anymore, the air in the kettle is not expanding, and therefore, no noise.

There are at least two ways to lower your pitch.  First, many people hold their heads tilted up when speaking.  This makes it difficult to lower your pitch.  If you naturally hold tilt your heat up, make sure your head is tilted forward.  Second, you can lower your pitch by moving the larynx down in your throat.  The larynx is the place where the speech sound originates; you can find it by touching your "Adam's apple".  If you concentrate, you should be able to actually physically move your larynx down, which will lower your pitch.\n\nTo decrease the rate of your speech, make the pauses between phrases longer.  Native speakers of English naturally make pauses in between phrases.  Making these pauses in the right places will give the impression that you are talking slower, because people will have more time to think after you've said each phrase.  In general, make a pause after a key word, every three to five words or so.\n\nPeople who are really good at this are newscasters.  You can practice by listening to news programs and imitating their pitch and rate.

seat the head evenly & press down in middle of head w/finger..lightly, tap at each tuning lug opposite of each other & tighten or loosen until they're the same tone, note, the bottom head should be slightly higher in pitch. for further specifications of directions, feel free to contact me at my email address.

Let's make some assumptions:\n1. The cups are the same size, shape, etc\n2. The amount of hot tea is equal.\n3. Both cups are in the same room at the same temperature conditions\n\nThe laws of thermodynamics state that temperatures will seek equilibrium at a rate proportional to the difference between those temperatures.\n\nSo, by adding milk to one cup, you are slightly lowering the temperature of the tea. So, the milk tea will cool at a slower rate than the other tea because the difference in room temperature and the temperature of the milk tea is less than that of the other tea. \n\nFinal answer: cup of tea

I like the taste of two teas and both of them are great as iced tea.\nThey are 'Arctic Fire' and 'Blue Lady'.\n\nArctic Fire\n   Description\nBlack tea combined with cornflower blossoms and a unique peach and pepper taste. There are also citrus notes.\n\nBlue Lady Tea  \n Secret blend of passion fruit, grapefruit and X'. Very refreshing with tangy notes\n\nThey can be obtained from good loose leaf tea shops or ordered online.

Depends upon the volume.

because the liquid you are stirring is being changed chemically,\nbecause what you are stirring in is becoming 'part of'\nthe liquid in the cup therefor it changes the exerted pressure on the inside of the cup which in kind changes the harmonic resonance of the cup, hence the change in pitch of the clinking. you can test this by stirring your coffee before you add anything and then after/as you add your sugar and/or your creamer

They measure the frequency of vibrations, which are in direct correspondence to the pitch.  If the number of vibrations are off, so is the pitch.

Here's a link to some very informative fast pitch material which, in chart form, nicely presents situations for a pitcher and recommended pitch types and placement. I'm sorry, it is much too detailed to recap for you here, but I recommend that if you are serious about being an effective fast pitch chucker, you place the link in your favourites or print it out. ty.

Music is organized sound, so I think the answer would be "irregular vibration patterns".  These links should help.
