This lab experiment was conducted in order to test the speed of sound, which is the distance traveled per unit time by a sound wave. This experiment was carried out with a certain setup, which involved materials such as a computer, a Logger Pro, a vernier microphone, two tubes, a temperature probe, a meter stick, and a dog trainer clicker. These materials were set up in a specific fashion, the Logger Pro was connected to the computer, which allowed for a temperature reading. The microphone was then
understanding how wavelength, frequency, and velocity work together it is important to know one equation: velocity = frequency x wavelength. Also, it is important to know that in order to see how the speed of sound depends on temperature, it is important to know that at 0 degrees celsius, the speed of sound is at 330m/s. In order to add or subtract degrees, you would add or subtract 0.6 from 330. In regard to harmonics, it is important to see a theme between all. The first harmonic is
around since the beginning of time. Animals have used this technique and survived because of it for millions of years. Among the most common are bats and dolphins. Daniel Colloden used a bell to measure the speed of sound underwater in 1822. After the Titanic sunk, the idea of using sound underwater to locate objects, primarily icebergs, was taken up by inventors. Lewis Richardson, a meteorologist, was the first to file a patent for an echo locator one month after the Titanic had sunk. In 1914
will investigate the properties of mechanical waves such as a longitudinal wave, focusing on the question: Does a change in the frequency of a wave result in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory. Student Designed Investigation Procedure/ Planning Procedure: 1. Three students would get into a group. 2. A Slinky would be
necessitating a high AOA is the most likely situation to cause a low-speed Mach buffet. The situation that increases, the angle of attack, the speed of the airflow over the wing, and chances of Mach buffet are (FAA, 2008): Higher altitudes—the higher aircraft flies, leaner the air and the greater the angle of attack is necessary for producing the lift needed to preserve the flight level. Heavy weights—the heavy aircraft, lead to greater lift from the wing and larger angle of attack. Supersonic
Speed detection is one of the most notorious functions of our local and state police. How do they know how fast we are going? Speed determination is accomplished in two basic ways. First, the least sophisticated method is dependent upon an officer's ability to guess your speed. Second, either some electronic method using radar or laser instrumentation authenticates that officer's guess. As you will see, their guesses are usually right on target. What does this mean for you? Usually a
An experiment to find the acoustic impedance of paraffin and water Abstract The speed of sound through paraffin and water was measured, and came close to the generally expected value. The speed in was calculated as 1458.36±16.2ms^(-1) in water and 1212±23.7ms^(-1) in paraffin. Then the density of these two liquids was measured, and combined with the speed of sound to find the acoustic impedance. . The acoustic impedance of water was 1575±29kgm^(-2) s^(-1) and the acoustic impedance of paraffin
Sound is made when something vibrates. The vibrating body causes the medium water and air around it to vibrate. Vibrations in the air are traveling longitudinal waves, that we can hear. Sound waves are in areas of high and low pressure called compressions and rarefactions. Lighter areas are low pressure rarefactions and darker areas are high pressure compressions. The wavelength and the speed of the wave figures the pitch, or frequency of sound. Wavelength, frequency, and speed are related by the
Music, one of the most beautiful sounds on Earth, the strumming of a guitar, the vibrations of reeds in a saxophone, the vibration and the pressure in between the two heads of the drums, the vibration of the bass chords. Every single thing has its own sound, some of those can not be heard because of the low or the high amount of hertz, and can only be heard by another type of animal that can actually hear that amount of frequency for example whales can hear a very high frequency while dogs can too
maintain the speed of sound for great distances. Engineers have designed a brand new aircraft known as the F-22, which has the ability to fly an entire mission at supersonic speeds. The speed of light is unattainable by aircraft due to drag. We have no materials that could with stand the heat caused by the friction of the air moving over its body, nor materials strong enough to be able to take the enormous drag. Today there is no thrust capability that would allow for the speed of light. Although
The Physics of the Sound Wave and its Effects on the Human Ear Could you imagine living in a world without sound? It would be enormously different from the world that we know. Our primary form of inter-human communication would be based on visual or tactile imagery. Our sense of perception would be changed. Telecommunication would be different. We would not have the pleasure of music or the soothing sounds of nature. Sound has had an immense impact on our world. This essay will explore the unseen
RADAR RADAR is a term is used to refer to electronic equipment that perceive the presence, course, altitude, and distance of objects by using reflected electromagnetic waves. The term radar is in fact an acronym made up of the words radio detection and ranging (RADAR = RAdio Detection And Ranging). The fundamental basics of RADAR is built upon electromagnetic radiation. RADAR utilises radio waves which is a type of electromagnetic wave on the electromagnetic spectrum. RADAR finds target objects
disadvantages will be studied. All forms of non-radio communications are based on waves. Waves are generally a disturbance in a surface, transferring energy from A to B. Waves can be mechanical vibrations travel through a medium. For example: water, sound. These waves are called mechanical waves. Progressive waves are created from a point and energy is distributed to the surroundings. For example: dropping a pebble in the middle of a pond causes energy to be distributed outwards. All waves can be

The eating speed of a person can be one of the important aspects of eating behavior. Time constraint might be one of the factors that influence eating speed.

Sound Files; In sound files, there are two type of sound file, the first one is .wav and the second one is .MP3. The wav file is a high sound quality however it is a
Effect is a wave phenomenon that can be heard every day. It affects different sound differently depending on their sources’ speed relative to the observer. I noticed this when I observed that if the source moves too slowly, the effect is less apparent. I wanted to explore this situation, and to fulfill my curiosity, I used a sound emitter traveling in a circle. I asked this question: “How does the angular velocity of a sound emitter traveling in a circle affect the range of frequencies heard by a fixed
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. WAVELENGTH is the distance from one point on the wave, to the next identical point, or the length of one part of the wave.

Submarines have been around for longer than most people think. The first American attempts at creating a submersible boat date back to the days of the Revolutionary and Civil Wars. These boats, however, turned out to be just as dangerous to the people on board as they were to the enemy boats. So the concept was put aside for a while. But in the 1890's two men named John Holland and Simon Lake built a practical underwater boat. The US Navy bought its first submarine from Mr. Holland on April

Modern technology may have finally caught up with the dream of Mach speed commercial airline travel is possible and new designs are back on the drawling board. In this paper we will explore the dream of traveling faster than the speed of sound and examine the benefits and hurdles of utilizing super sonic commercial travel. In order to even attempt
