Nthis example we will look at the periodic motion of an ultrasonic transducer, a kind of ultrasonic loudspeaker used for medical diagnosis. the transducer is oscillating at a frequency of 6.7 mhz (6.7×106hz). how much time does each oscillation take, and what is the angular frequency?

How will the system respond to a temperature increase?

This is the number of complete movements of a wave per second.

Afisherman notices that his boat is moving up and down periodically, owing to waves on the surface of the water. it takes a time of 2.70 s for the boat to travel from its highest point to its lowest, a total distance of 0.700 m. the fisherman sees that the wave crests are spaced a horizontal distance of 6.50 m apart. a. how fast are the waves traveling? b. what is the amplitude a of each wave?
