Direction: Write the given and formula. Show your complete and detailed solution. Calculate the frequency of a sound wave with a period of 2.27 x 10-3. After that, find the (a) period of vibrations and (2) angular frequency. A sound source producing 1.00 kHz waves moves toward a stationary listener at one-half the speed of sound. What frequency will the listener hear? A car alarm is emitting sound waves of frequency of 520 Hz. You are riding a motorcyle travalling away from the car. How fast must you be travelling if you detect a frequency of 490 Hz.
