Standing wave

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…

(done with the plane, building bridges), ocean waves (done with the ship in the sea), and ground motion because of the earthquake (action and building structures). The general two kinds of vibration are free…

So far, I have listened to all the entries of the historical recordings of The Vancouver Soundscape. Track one is a recording of ocean sounds. The listening process has been an enjoyable experience to me, for I have never ever listened into the ocean sounds before. I have heard four types of ocean in track one. When I click to start, I hear sea-water lapping against the sea shore gently. The ocean sings a “ sha-la-la-la ” and there is no wind. All I can hear is the patting of water, clear and…

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;…

Night-time and The Wave, two characters had to make some very important decisions. It was difficult because they both didn't have much experience in trying to make decisions that others didn't agree with. In The Curious Incident of the Dog in the Night-time, Christopher had to make some very tough choices such as leaving his father to go live with his mother in London. In The Wave, Laurie, a senior at Gordon High had to make a decision no one agreed with. She didn't want to be in The Wave. So…

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”…

An immense blue wall was blocking my view of the breathtaking sunset. The air was moist. I was in Maui, Hawaii. Everyone was yelling, screaming, hollering and having fun. Kids were flying their kites. People were eating pizza and icecream. Then suddenly, everything became quiet. Everyone was looking at me. The wave broke the silence as it jumped on me like a tackle in football. I felt like I had the ball because I kept getting tackled by the water! I was wobbling in the water and trying to…

the other kids that played on my team, and almost as good as the kids that played on official teams with their schools. I’m pretty sure I was that teams star player. I looked over at the coach. He seemed to be watching me-probably because I was doing so well with the drills and he wanted to use me as an example of excellent form. I waved to him. Coach The coach looked over the field of ___ 10-year-olds with a sigh. Liz was tripping over the ball trying to dribble it across the field again.…

 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…
