Using a Strobe Light to See Resonance of Wine Glass
Using a strobe light to see the resonance of a wine glass is a great way to identify the resonant frequency of your wine glass. There are a few methods that you can use, including dragging your finger on the rim, or by using a driving signal generator. a post on the Strobe Sport`s blog can also use a chromatic tuner to find the resonant frequency.
Dragging your finger on the rim
Using your finger to drag your wine glass along its rim is an interesting way to produce a musical note. It can also create a symphony of sounds. When dragging your finger on the rim of a glass, you are creating a resonant vibration, which is a small wave.
The resonant wave travels through the air, which is picked up by your ear. The sound wave is similar to the one created by tapping a glass. However, the resonant wave is smaller, and has a lower frequency. The resonant frequency of a wine glass is within range of human hearing, from 20 to 20,000 Hz.
Using your finger to drag your wine glass around its rim creates a small wave of friction. This produces a sound wave, which is the simplest form of vibration. When the finger is removed, the glass continues to vibrate.

Using a chromatic tuner
Using a chromatic tuner to see the resonance of a wine glass is a great way to teach kids about music and the different notes. The trick is knowing how to apply the right amount of pressure to the right areas of the glass.
The resonant frequency of a glass depends on the liquid and the density. For example, the denser the liquid the more energy it takes to make the waves that produce the sound.
Using a chromatic tuner can be used to determine the note a wine glass makes when hit with a metal spoon. This is because the metal spoon generates the same wave pattern as tapping a finger.
To generate the best sound with your fingers, you will need to wet your index finger and apply some pressure. Do this by rubbing the glass rim gently. You may need to repeat this process several times to get the same result.
Using a driving signal generator
Using a driving signal generator to see resonance of wine glass can be a great way to teach students about the science of sound waves. In this activity, a speaker, a microphone, and a spectrum analyzer are used to demonstrate the effects of acoustic vibration.
Initially, students will be introduced to the concepts of resonance and dampening. They will then be taught how to tune a driving signal generator to a specific frequency of a wine glass. This is a key step in the demonstration. The student will need to perform this task before the lecture begins.

The amplifier is then switched to a frequency synthesizer input. The acoustic energy is then transferred to a microphone. This microphone is then connected to an oscilloscope. The acoustic signal is then increased to excite the vibration of the wine glass.
Finding the resonant frequency
Getting the resonant frequency of a wine glass with a strobe light is a bit tricky. This is because the resonant frequency of a glass depends on many variables.
For example, the amount of water and the density of the liquid are two factors that will affect the pitch. Some glasses will be more resonant than others.
The resonant frequency of a wineglass is within the range of human hearing, from 20 to 20,000 Hz. This corresponds to a 200Pa pressure perturbation. A loud noise at this frequency would be painful for listeners.
The resonant frequency of wineglasses varies from type to type. Most glasses will have a higher frequency. This is because the molecules of the liquid in the glass are arranged in an amorphous structure. This makes it very brittle. Eventually the glass will shatter.
The resonant frequency of the glass is also affected by the size and shape of the glass. For example, a small glass is more likely to be resonant than a large glass. A high-quality glass will have a long, pure tone. A low-quality glass will have a shorter, duller tone.
