Document Summary
Speed of wave and frequency and wavelength relationship. Displacement of wave as a function of space and time. Newton"s 2nd law of string under tension wave equation. Objects coupled and each object undergoes simple harmonic motion. Situation a taut string moving up and down sending waves, each part of the string moves the same way as the end of the string being moved up and down, just at a different time. Though there is a velocity of the wave, the string does not go anywhere. The string is the medium of which the wave travels. A wave travels through the audience but the people do not go anywhere. Transverse waves - motion of any part of the medium at any given time is perpendicular to the direction in which the wave moves. K = wave number y1 = a cos( t)
