Review Unit #1 1 Physics 1251 Unit #1 Fundamentals of Sound Review Sheet o Longitudinal waves move along the direction of propagation of the wave. o Transverse waves move perpendicular to the direction of propagation of the wave. o Sound is a longitudinal pressure/displacement wave with frequency from 20 Hz to 20 kHz . o Pressure is the force per unit area. o { p = F/a } unit: Pascal [Pa] =[N]/[m] o S o u n d r e q u i r e s a medium such as air, water or solid to propagate. o The velocity of sound is determined by the square root of the ratio of the “springiness” to the “inertia” of the medium. v = vB/? for example. o L i g h
