The experiment could be changed to have a more accurate answer if more frequencies were tested. This would give a wider range of frequencies to make absolutely sure that every frequency as it gets lower the wavelength gets longer. This experiment answered my primary question with specific and meaningful data. The scientific principles that can be learned from this experiment is that as frequency goes lower the wavelength gets longer. Another scientific fact that can be learned from doing this experiment is that sound waves are caused by vibrations moving through substances' in this experiment that substance was water. Another scientific fact that can be learned is that sound moves through water very well. What other substances can sound move through well? Conclusion The data supports the hypothesis "If the frequency of a sound increases, then the wavelengths of a sound will decrease, because the wavelength is the speed of sound divided by the frequency." The experiment supported the hypothesis because the experiment showed that the relationship between wavelengths and frequencies is as hypothesized. In all cases, as frequency increased the wavelength decreased. When the speed of sound is divided by the frequency the calculated wavelength was not equal to the measured wavelength. This difference is because standing waves were used for measurements and standing waves do not have the same constant as the
These averages we determined from the trials can be compared to the accepted speed of sound (344.2 m/s in this specific temperature), and we determine the relative error percentages:
Both scientists made the prediction that if wasps were tested at a frequency of 42,000 Hz, the following outcome would be observed.
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.
An Ultrasound Technician, also known as diagnostic medical sonographers, use high-frequency sound waves to create images of soft tissue in a patient's body. Physicians use these images to diagnose abnormalities and diseases in a patient. As early as 1826, a Swiss physicist name Jean-Daniel, had effectively used an underwater bell to determine the speed of sound in the waters of Lake Geneva. In the late 1800s, physicists were working successfully towards defining the fundamental physicists of sound waves, transmission, propagation, and refraction. Lord Rayleigh was the first to describe sound waves as a mathematical equation, forming the basis of future practical work in acoustics. Lord Rayleigh famous work “the Theory of Sound” was published
As the hearing is one of the most important ability a person can have it has a great deal of benefits. This allows an individual to hear sounds from a mechanical wave which is then transferred to stimulate the hearing organs inside the body. The mechanical wave is only able to transfer energy through a medium, the two types of waves that associate with the mechanical is both the longitudinal and the transverse wave.
It is often overlooked that the Baillie sounder worked as a system with other instruments. In addition to the sounder, several thermometers, a water collection bottle and a pressure gauge were often attached to the hemp sounding line. In this manner, the Baillie sounder worked in concert with several other instruments collecting information about the ocean floor.
In order to provide the Australia Park Victoria with the appropriate data to solve its current crisis, the most appropriate method of data collection for this research is the qualitative method. According to Gay and Airasian (p 627) qualitative method is the collection of extensive data on various variables over a long time in a natural setting with an aim of acquiring insights not possible using other methods. It involves three different kinds of information collection: direct observation, in depth and open-ended interviews and written documents. Qualitative method involves use of random sampling and structured data collection instruments that fit different experiences. The method also enables the researcher to study the specific area of
The sensory energies of light and vision and sound vibrate as waves passing through space. These waves result from reflected light or from changes in air pressure caused when vocal cords and other stuffs move. Generally eye and the ear identified the waves as light and sound. The waves of light and sound can describe in term of wavelength, frequency and amplitude. Wavelength is the distance from one peak of the wave to the next. Frequency is the number of complete waves or cycles that pass a given point amount of time. Amplitude is height of the wave from baseline to peak. These are shown in the Figure 3. The different wavelength, amplitude and frequency makes various sound and vision experience.
HS-PS4-1. Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media
Burt Stephens 01-15-2015 Super Senses Purpose: The purpose of this lab is to tune your senses of sight and sound. Introduction: Sound is created when energy travels as waves of pressure through matter such as air, water, or even solid materials. Virtually everything that vibrates can yield sound. When something oscillates it pushes the particles around it, and those particles in turn push the air particles around them, moving the pulse of the vibration in all directions from the source.
And both forms of entertainment of radio and television broadcast has much to do with sound behavior. And this video being heavily integrated with sound, an aspect of physics. To my belief, this video was design to persuade or to catch the interest of young Americans to be familiar or to pursue a life into STEM fields. To encourage students to learn math, science, physic, engineering. To change the world in the hearth of America.
Q 9. Even if your results do support the experimental hypothesis, give three major possible
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
Sound is defined as the movement of air molecules brought about by a source of vibration. The ear works by picking up sound waves vibration in the eardrum, which is located inside your ear. Then the sound waves are carried through a fluid in the inner ear called cochlea, this process turns and vibrates tiny hairs that tune to different pitches of sound. Information from the vibration of the hairs stimulates nerves is then sent to the signals of the brain to be processed. The ear is similar to a microphone where sound vibrates a diaphragm, which causes electrical signals to travel through a wire to a processor. Sound is made up of characteristics which are pitch and loudness. Pitch is known as the tone of a sound wave that is
