A sound wave is a disturbance that repeats regularly in space and time and that transmits energy from one place to another with no transfer of matter. In Activity 2 on page 8 we had to model sound waves using an instrument. In our class we used a flute as the example and when the person blew into it, sound waves were produced. As they blew and changed the volume and pitch the sound waves changed. A sound wave is created when something vibrates. When something vibrates, longitudinal waves are created which we can hear. A longitudinal wave is a wave that transfers energy through compressions and rarefactions in the material that the wave travels which are all parts of a sound wave. In Activity 2 it states in some parts of the wave, the air molecules

In this lab, we will be doing 3 major things: 1) Collecting and organizing data to obtain resonant points in a closed pipe, 2) measure the length of a closed-pipe resonator, and 3) analyze the data to determine the speed of sound.

The sound waves are produced by a random oscillating crystal, and are inaudible to humans. A instrument called a

This essay will reflect my thoughts on chapter 9. In brief this chapter deals with how the ears allow us to be able to hear and process sound. When I first think of sound I think of the frequency. This makes me think of songs that I listen too in order to determine it 's a high frequency or a low frequency. I 'll be able to determine the amount of hertz that are in songs on the radio. I do feel that it would be hard to determine because most of that music is reordered, hearing people sing a cappella would be easier to determine the amount of hertz present. I know what hertz are, but I 'm still not sure how they are actually determined? Are they sounds just determined by our brain if we have unimpaired hearing. How would someone like my brother with a whole in his ear be able to determine frequency?

In Special Glasses, Billy Collins utilizes humor and a lighthearted tone to create a much darker theme involving death and loss.

The purpose of this experiment is to measure the speed of sound in air and to determine the effects of frequency on the speed of sound.

The snail like shape of the cochlear effectively boosts the strength of the vibrations caused by sound, especially for low pitches. When sound waves hit the ear drum, tiny bones in the ear transmit the vibrations to the fluid of the cochlea, where they travel along a tube that winds into a spiral. The tube’s properties gradually change along its length, so the waves grow and then die away, much as an ocean wave travelling towards the shore gets taller and narrower before breaking at the beach.

Then, measure the absorbance at the time that was decided as the optimal in step four.

Have you ever wondered why glass bottles made a sound, kind of like a music note? Well, this paper will explain how this works. The paper will be talking about sound, sound waves, standing waves, musical note names and frequencies, resonance, and closed-end air columns. Closed-end air columns will be a main focus in the paper, studying the physics behind it. Glass bottles are an example of a closed-end air column. Therefore, the more water inside the bottle, the lower the note, and less water would be a higher note.

It is within this framework that I consider important to study the way in which sound is

What is a sound wave? A sound wave is produced by a mechanical vibration, such as a tuning fork. The vibrating object causes the surrounding medium, such as air, to vibrate as well.The wave travels through the medium to a detector, like your ear, and it is heard.As with any type of wave, a sound wave is also described by it's wavelength, amplitude, period, and frequency.

This experiment shall be repeated twice or more to enhance accuracy of the results obtained. Besides detecting systematic errors, this experiment would aid on the technique and understandings to the correct use of these equipments.

Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves. It is a high pitch frequency that cannot be heard by the human ear. In ultra sound the following happens: High frequency sound pulses (1-5megahertz) are transmitted from the ultrasound machine into your body using a probe. The sound wave will travel into your body until it hits an object such as soft tissue and bone. When the sound wave hits these objects some of the wave will be reflected back to the probe. While some waves may carry on further till they hit another object and then reflected back. The probe picks up these reflected sound waves and relays them to the machine. The distance and time from the probe,

One of the most used materials in human history is glass or more specifically silicate glass. Although some types of glasses are called crystal glass, glass is actually an amorphous solid and does not have a crystal structure. It is used in all walks of life ranging from homes to automobiles to laboratories. Historically, the one of the first types of glass that was used by humans to make tools and weapons was the volcanic glass known as obsidian. As for manmade glass, the earliest accounts date back to 5000 BC in the middle east. Primitive methods of glass making were used until about 100BC, when glassblowing was believed to be discovered. This discovery made glass products popular in the Roman Empire since the development of glassblowing allowed glass production to be more efficient and thus less expensive. As the centuries went on more techniques were developed which eventually lead to glass products being widespread. This paper will discuss some of the methods of glass production throughout history, the types of silicate glass, and the different ways that glass can be colored.
