    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

    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

    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

    behavior. The theoretical framework of developmental and life course theories of crime allow for the addition of the dynamic element of time and places an emphasis on the longitudinal processes of how the interaction between the individual and his or her social environments constrain and influence behavior. This longitudinal perspective opens up the possibility that the peer social environment is one that is dynamic. Friendships can be added and terminated resulting in the number of friends reported

    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

    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.

    Physics Waves Lab SL Introduction: This lab 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
