Unformatted text preview: periodicity T(=repetition time) and travels as a disturbance through the medium with a spatial periodicity called “wave length” λ (repetition length) – At any given location on the path of the wave the local medium moves with period of motion Period T – The pattern of the disturbance repeats itself along the direction of its motion with repetition length called wavelength: λ – Clearly these relate to the propagation speed as; v= λ / T= λ f Traveling Wave Function y(x,t) • SHM of “waving” particles of the medium is particularly simple, and both the movie of the motion and the shape of the traveling disturbance will be sinusoidal functions. • Denoting the “disturbance” (e.g. the transverse displacement of a string) as y, a function of two variables position x and time t, we eed to find y(x,t): – At a fixed point x=x 1...
