PCS 125 Lecture Notes - Lecture 12: Longitudinal Wave, Wind Wave, Seismometer
Document Summary
A traveling wave or pulse that causes the elements of the disturbed medium to move parallel to the direction of propagation is called a longitudinal wave. Sound waves are another example of longitudinal waves. The displacement of the coils is parallel to the propagation. Some waves exhibit a combination of transverse and longitudinal waves. The elements of water at the surface move in nearly circular paths. The disturbance has both transverse and longitudinal components. Fastest, at 7 8 km / s. Transverse a seismograph records the waves and allows determination of information about the earthquake"s place of origin. The shape of the pulse at t = 0 is shown. The shape can be represented by some mathematical function, y (x,0) = f (x). This describes the transverse position y of the element of the string located at each value of x at t = 0.
