Sound Waves Essay

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

A sample of gas at 6.0 atm and 5.0ºC increases in temperature to 35ºC. If the volume is unchanged, what is the new pressure?

The difference between the two specific volume values gives the volume change per gram of

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

In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.

The pressure of a gas sample increases for a decrease in volume and decreases for an increase in volume.

So, plugging in a value from the temperature/pressure data, and the value obtained for Subscript[\[CapitalDelta], vap]H, we

Sound waves are caused by disturbances in the air. These disturbances are usually caused by a vibrating object. In the case of the MTCC, the CTA train railroad is right above the MTCC. As the train is traveling along

“In physics, pressure is defined as the force over a given area” (Nelson). There is a formula that might help someone if they want to know how to measure the pressure and the formula is Pressure = Force/Area. The state or the

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.

 is the total pressure (the sum of the static pressure p and dynamic pressure q).[10]

Sound is a wave, and a wave can be remembered as a medium, carrying energy from one point to another. The sound wave has a resemblance of a slinky in its nature, for many reasons. The disturbance goes from one place to another, carried by the medium. Typically, the medium will carry energy through the air, although it could be any substance like water and steel. There is an original source of the wave; anything from someone’s vibrating vocal chords, or a tuning fork. Then, the sound is transported through the medium through particle-to-particle interaction. If the sound wave is moving through the
