In this example we will look at the periodic motion of an utrasonic transducer a kind of uhrasonic loudspeaker used for medical diagnosis. The transducer is oscilating at a frequency of 6.7 Mis 6.7 x 10 Hay How much time does each oscillation take, and what is SOLUTION SET UP We first identify the frequency: -6.7 10 H-6.7 x 10 SOLVE The period is given by T-1/f and the angular frequency by u-2mf T- 15×100.15 store 2f-2(6.7x10 He) 4.2 x 10 rad/s. REFLECT The transducer's rapid vibration corresponds to large values off and u and amal values of 7. The reverse would be true er a slow oscillator the pendulum of a large grandfather clock Part A Practice Problem: Suppose the traducer was aunted so that it osciated with a period of 60 j.
