• ## Helmholtz Resonator Lab Report

A common example of a Helmholtz resonator is a bottle because it has a set volume as well as having an opening which is open to the surrounding air. By considering the Helmholtz resonator as having a neck, such as the neck of a wine bottle, the dynamics of the system may be described. When energy is introduced near the opening of the bottle, for example blowing across it, some of the energy will vibrate the cylindrical plug of air inside the neck of the bottle. This plug of air is assumed to move as a unit. This movement is due to the driving force of blowing across the bottle, the elastic force on the inner end of the plug, and the dissipation force. The top of the air plug acts as single source when it oscillates and will create sound waves. This vibration of the air is due to the springiness of the air. When the air plug is compressed by blowing across the top it increases the pressure inside the bottle and then it bounces back to its original volume. The frequency at which the air inside resonates is unique to the shape of the bottle and depends on the length of the neck, the diameter of the opening and the volume of the bottle. No matter how much energy is introduced, such as blowing soft or hard across the opening, the bottle will produce the frequency which is unique to it. Theory To create a useful equation to estimate the resonance frequency of a bottle, three forces must be combined. Newton’s second law can be used to find the elastic, dissipation, and driving…

as printed circuit boards. Printed circuit boards can be used for just about anything from power dividers to filters. Ring resonators are used to find microwave substrates produced in the ring resonators and can be antennas to circuit boards. The FR4 Ring Resonator is used for devices similar to switches and transformers. Microwaves are a major part of this lab and are electromagnetic radiation in a form of waves. Microwaves are used in in some devices resembling radar, heating devices, radio…

• ## Personal Narrative: My Trip To Mexico

March, my family and I took a trip to Mexico for vacation. We did many fun things down there such as; parasailing, went on a boat for a day trip, sail boating, went swimming in the ocean, buggy board, sand volleyball, swam in the pool, walked the beach at night, got henna tattoos, a dread in our hair and went to the club with my brother and Emerson. The sand on my feet, the crashing of the waves, people swimming in the ocean, the smell of sunscreen and the wonderful taste of my flamingo drink;…

• ## Sound: A Periodic Wiggle In Time

up of vibrating waves that move up and down back and forth. Two ways to think of sound in a real life example are: 1st a slinky; the way it jiggles back and forth is much like how a sound wave can jiggle, 2ond a water wave; the way that the wave looks much like a squiggly horizontal line that is what sound waves act much like. A vibration, A.K.A the up and down slinky motion and the to and fro water wave motion, are called vibrations. A definition of vibration is “ A periodic wiggle in time”…

• ## Light And Objective Lens Essay

When a lens produces an image, the size of it corresponds to the focal length of the lens. The smaller the focal length, the smaller the image and the longer the focal length the bigger the image. How bright an image may be solely depends on the amount of light collected by the objective lens. How much light can be collected corresponds to the area of the objective lens. So the bigger the objective lens, the more light can be collected. If you want to increase the light gathering power by 4, you…

• ## Comparing Math In Relation To Harmonics And Tonal Color Of Instruments

 Musical Notes Can Count Jerri Pineda Abstract— The development of mathematics involves early connections with music and the basic physics of sound. Mathematics is present in the natural occurrence of the ratios and intervals found in music and modern tuning systems. As people age, their hearing becomes dull and require change in the music ratio and interval to hear the same tune as when young. In like manner, the interval increases until a perfect pitch is heard. In this paper we will examine…

• ## Ben Ross The Wave Analysis

The Wave is all about types, and Robert Billings is no exception; he's the school loser, to use the novel's rather cruel terminology. Other students in the school are afraid to ruin their own image by hanging out with the “class creep”. Ben Ross thinks that part of his problem is living in the shadow of his ultra-popular brother, who used to attend Gordon High School. When the Wave finally comes along, Robert seizes the opportunity to make a change, but things get even worse. Although some might…

• ## Sound Waves Research Paper

the branch of physics concerned with the study of sound. Sound is a wave made of vibrations in the air. Waves can be measured in a range of different ways: by their amplitude, wavelength, frequency, speed, and, at times, their phase. Sound information is transmitted by the amplitude and frequency of the vibrations, where the amplitude is experienced as loudness and frequency as pitch. The vibration is started by some mechanical movement and this causes a vibration on the molecules next to the…

constant movement of people. It reminds her of the sea at high tide, when the waves are strong enough to knock you off your feet. At that moment Sarah is swept along, floating on the crest of the wave towards the train, bobbing along the platform buoyant with hope. Confusion, sadness and panic floating away with every wave she rides towards the train. Boarding the Grand Central train heading North on autopilot her head filled with anticipation and optimism. The train starts to move. The noise,…
