In Physics, a wave is essentially defined as the motion or movement of a disturbance. Some waves, such as sound waves, require a medium through which the disturbance travels; for example, when a disturbance (essentially an applied force) is made in a lake, the water is the medium through which the disturbance travels. Thus, the water particles will be in motion when the disturbance is made. Other waves, such as radio waves, do not require a material medium, but rather, can travel through a vacuum
the word wave? Maybe you picture yourself waving your hand to say hello, or a wave on the ocean. In physics, a wave can be defined as a a repeating and periodic disturbance that travels through a medium and transfers energy from one point to another. This disturbance, or variation, can move up, down, forward or back, just think of the waves in the ocean. The medium is the substance or material that carries the wave, for instance, with ocean waves the medium would be the water itself. Wave motion transfers
Sound is a product of mechanical waves that initiates the natural frequency of an object. This natural frequency sends out vibrating waves that we hear as sound. In order to better understand mechanical waves and electrical impulses you must first be able to understand the properties of waves, speakers and electrical signals. A key component that is crucial in understanding sound is waves. There are two types of mechanical waves, longitudinal and transverse. In both waves the particles must move with
the Speed of Water Waves Introduction In this experiment I will be investigating the wave speed, of waves on water in a tray, and how this speed is affected. Waves can be longitudinal, when the particles move in the same direction as the direction of the wave, or it can be transverse, when the particles move at 90o to the direction of the wave. Water waves are transverse waves even though transverse waves cannot travel through liquid. This is because the waves travel on top of the
broadcasted with both microwaves and longer radio waves. These are transmitted in two ways: amplitude modulation (AM) and frequency modulation (FM). Amplitude radio is created by combining a sound wave from a microphone, tape, record, or CD with a "carrier" radio wave. This results in a wave that transmits voice or programming as its amplitude (intensity) increases and decreases. Frequency modulation conveys information, voice, and music on a radio wave is to slightly change, or modulate, the frequency
the shape of the lens, he discovered the cause of astigmatism, and he and Helmoltz initiated the three color theory of perception. In 1801, regardless of the uncertainty from other scientists, his double-slit experiment established that light was a wave motion, making his famous. Over the years, he gained new interests. He started studying Egyptology, and while he was one Napoleon’s expeditions he started studying the texts of Rosetta Stone. This in time helped to decipher the ancient Egyptian hieroglyphic
different tone qualities and the ability to be played in a certain way to produce a specific pitch or note. Music is sound, and sound is vibrations or waves that are at the right frequency to be perceived by the human ear. Audible vibrations are waves with a frequency between 16 and 20,000 vibrations per second. So what causes sound waves? Sound waves are caused by a disturbance in an elastic medium. These can include the strings on a violin, the reed on a clarinet, and even the human vocal cords.
Acoustic Waves in Physics An acoustic wave can simply be described as a longitudinal wave. A longitudinal wave is a wave that vibrates and moves in the direction of its propagation. This means the medium is either in the same or opposite direction of the way the wave travels. Acoustic waves are a form of Mechanical longitudinal waves; these waves are otherwise known as compression waves or compressional waves. Compressional waves obviously produce compression, decompression, and rarefaction to
INTRODUCTION Electromagnetic waves propagate in waves with several measurable characters, namely: wavelength, amplitude and speed frequency. The amplitude is the wave height, whereas the wavelength is the distance between the two peaks. The frequency is the sum waves passing through a single point in a single unit of time. The frequency depends on the speed of wave propagation. hence, the speed of the electromagnetic energy is constant. Electromagnetic energy has a very important role in everyday
of shock waves. Two are classified as body waves which means they travel through the earth's interior and the other four are surface waves. The waves are changed by the rock types or formations they hit. Primary or compressional waves (P waves) send particles moveing back and forth in the same direction as the waves are traveling, secondary or transverse shear waves (S waves) send vibrations perpendicular to their direction of travel. P waves always travel at higher velocities than S waves. Three general

It has a frequency higher than the higher human auditory check of 20 KHz.[1] Ultrasound frequency is described as the number of ultrasound waves each subsequent, and health ultrasound mechanisms use waves alongside a frequency fluctuating amid 2 and 15 MHz.[2] The velocity of ultrasound in a specific medium equals the frequency of ultrasound increased by its wave length.[1] Go to: BASIC PHYSICS
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. AMPLITUDE
the data actually showed that with every increase in pipe length, the amplitude got louder as well, thus refuting the hypothesis. These results made sense because what was created inside the PVC pipes was a standing still sound wave, or a resonance wave. These kinds of waves have certain locations on its wavelength in order for the change in sound to be heard, which it usually half a wavelength. With this, the tuning fork is 83.3Hz and a usual wavelength is about 300Hz, 300/83.3 = 3.6 meters, which
going through these mediums, the sound travels in waves known as longitudinal(figure 3) and transverse(figure 2) mechanical waves. The variations in sound are caused by the different frequencies of vibrations. The difference in the two types of sound waves is; a transverse wave travels just like when you make a rope go up and down, the waves move along in a vertical direction, whereas a longitudinal wave moves in a horizontal direction pushing the waves along. Sound is produced in a saxophone by
“A wave is a transfer of energy from one point to another with no transfer of matter.” (Walding Et Al, 1999) Waves that require matter to propagate are referred to as mechanical waves; whereas electromagnetic waves comprise of those that do not necessitate matter to propagate. (Walding Et Al, 1999) Mechanical waves can further be divided into two sub-branches: longitudional and transverse waves. Longitudional waves occur when the particles of matter used by the wave to propogate, vibrate parallel
of nature. Six kinds of shock waves are generated in the process. Two are classified as body waves, that is, they travel through the inside of the earth and the other four are surface waves. The waves are further classified by the kinds of motions they incur to rock particles. Primary or compressional waves, known as P waves, send particles moving back and forth in the same direction as the waves are traveling, as secondary or transverse shear waves, known as S waves, create vibrations perpendicular
2.6.2.2 Waveguide Dispersion The effective index varies with wavelength not only due to of material dispersion, but also because varies with . In turn, it varies with wavelengths. These implicit variations of [ ] with gives rise to the second cause for chromatic dispersion, which is term waveguide dispersive [D37]. The total dispersive are combinations of the relative contributions of waveguide dispersion and material dispersion for a conventional single-mode fibers. The zero-dispersive
4) Quality of Service- This attribute can specify bandwidth and end to end performance requirements. It uses SLAs that deliver end-to-end performance matching the requirements for voice, video and data over converged business and residential networks. This gives wide choice and freedom of bandwidth and QoS options. 5) Service Management- This gives ability to monitor, diagnose and centrally manage the network, using standard based vendor independent implementations. We can get rapid service provisioning
Refraction is the bending of the path of a light or sound wave as it passes across the boundary separating two mediums. If a wave of light travels from one medium to another the direction is changed. Refraction is caused by the change in speed experienced by a wave when it changes medium. A wave doesn't just stop when it reaches the end of a medium there will be some reflection off the boundary and some transmission into the new medium. The wave undergoes refraction as it approaches the medium. This
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 classed into two categories: * Transverse waves: In Transverse waves
