Summary: AMPLITUDE:The term 'amplitude' refers to the physical size of an oscillation.For sound waves in air,the amplitude is the maximum distance an individual air molecule will move from its starting point as a sound wave passes by. The amplitude of a sound wave determines its loudness. A sound wave ... can be [Expand Summary] AMPLITUDE:The term 'amplitude' refers to the physical size of an oscillation.For sound waves in air,the amplitude is the maximum distance an individual air molecule will move from its starting point as a sound wave passes by. The amplitude of a sound wave determines its loudness. A sound wave with a large amplitude will sound louder than a small amplitude wave. BIG BANG:The big bang theory teaches that at a specific moment, the universe began as a very small, extremely dense mass that exploded outward in a violent explosion.According to the theory, the universe is continuing to expand today as a result of this initial explosion.The observed red shift of distant stars and galaxies is one of the primary pieces of evidence for the big bang theory. BLUE SHIFT:The change in color toward the blue end of the spectrum due to an object's motion toward the observer. The blue shift is a result of the frequency of light waves coming from an object being affected by the Doppler effect. It is only noticeable when objects are moving at very high speeds. CONSTRUCTIVE INTERFERENCE:When two waves occupy the same space at the same time, their amplitudes add.If they add to produce a wave with a larger amplitude, they are said to be interfering constructively. DESTRUCTIVE INTERFERENCE:When two waves occupy the same space at the same time,their amplitudes add.If they tend to cancel each other out in doing so,the waves are said to be interfering destructively. DOPPLER EFFECT:The apparent change in frequency of a sound wave. The Doppler effect can be caused by the motion of the source of the sound,the motion of the observer,or by the motion of both. DOPPLER,JOHANN CHRISTIAN:(1803-1853).Austrian physicist and mathematician. J.C.Doppler first explained the Doppler effect in 1842. DOPPLER RADAR:Radar systems often utilize the Doppler effect to measure velocity.A light wave emitted atan object will be reflected back at a different frequency if the object is moving.The change in frequency can then be used to determine the velocity. EINSTEIN,ALBERT:(1879-1955).German-born American physicist.Einstein produced the theories of Relativity in the early 1900's that form the basis of modern physics. These theories gave scientists a different understanding of space and time, and also predicted the expansion of the universe. FREQUENCY:The number of oscillations per unit time. Frequency is commonly measured in oscillations per second, or Hertz. GLOBAL POSITIONING SYSTEM:A network of satellites which circle the globe and broadcast radio signals.These signals are analyzed by GPS units on the ground to yield information about position and speed. HERTZ:The unit of measurement for frequency.One Hertz, or 1 Hz, is defined as one oscillation per second. HERTZ,HEINRICH:(1857-1894).German physicist. HUBBLE,EDWIN:(1889-1953).American astronomer.Hubble's observation of the Doppler effect in distant stars and galaxies help form the foundation of modern understanding of cosmology.Hubble observed that distant galaxies and stars are red shifted and therefore must be moving away from us at very high speeds.These observations are direct evidence that the universe expanding. HUBBLE'S LAW:A mathematical principle that states that the velocity at which a distant star or galaxy is receding from Earth is directly proportional to its distance.The relationship is expressed in the equation v = Hod where v is the velocity of recession, Ho is the Hubble constant, and is the distance of the receding object from Earth.The precise value of the Hubble constant is not known. INFRASONIC:Below the frequency range of human hearing;below 20 Hz.Infrasonic sounds can be [Collapse Summary]

[Expand Summary] Human Anatomy and Physiology is designed for the two-semester anatomy and physiology course taken by life science and allied health students. The textbook follows the scope and sequence of most Human Anatomy and Physiology courses, and its coverage and organization were informed by hundreds of instructors who teach the course. Instructors can customize the book, adapting it to the approach that works best in their classroom. The artwork for this textbook is aimed focusing student learning through a powerful blend of traditional depictions and instructional innovations. Color is used sparingly, to emphasize the most important aspects of any given illustration. Significant use of micrographs from the University of Michigan complement the illustrations, and provide the students with a meaningful alternate depiction of each concept. Finally, enrichment elements provide relevance and deeper context for students, particularly in the areas of health, disease, and information relevant to their intended careers. [Collapse Summary]
