With a ruler. measure the wave- length and amplitude ofthe wave. a. Wavelength = b. Amplitude = 2. A kid on a playground swing makes a complete to-and-fro swing each 2 seconds. The frequency of swing is (0.5 hertz) [1 hertz) (2 hertz) \\ and the period is (0.5 second) {1 second) (2 seconds) . X 3. Complete the statements. A MARINE WEATHER STATION REPORTS WAVES ALONG THE SHORE THAT ARE 8 SECONDS APART. THE FREQUENCY OF THE WAVES IS THEREFORE THE PERIOD OF A 440'HERTZ SOUND WAVE IS SECOND. 4. The annoying sound from a mosquito is produced when it beats Its wings at the average rate of 600 wingbeats per second. a. What is the frequency of the soundwaves? b. What is the wavelength? (Assume the speed of sound is 340 rnls.) s3 -.- 5' A machine sun fires 10 rounds Pi5\"d' y: The speed ofthe bullets is 300 mi:- 3- What is the distance in the airbe mm is Increased? b- What happens to the distance between the bullets if the rate a j eed of the waves is 5- Consider a wave generator that produces iii pulses per second. The tip 300 cmls. a. What is the wavelength of the waves? ____.___. d? b. What happens to the wavelength if the frequency f pulses is increase 7. The bird at the right watches the waves. if the portion of a wave between 2 crests P113535 the pole each secOnd. what is the speed of the wave? ______._._ What is its period? I' ' 1'\" ___-' 8. if the distance between crests in the above question were 1.5 meters apart, and 2 crests pass the pole each second. what would be the speed of the wave? _________._--- What would be its period? ______.__--- 9. When an automobile moves toward a listener. the sound of its horn seems relatively {low pitched) (non-rial) (high pitched) . and when moving away from the listener. its horn seems tiow pitched) (normal) [high pitched) . 10. The changed pitch of the Doppler e'ect is due to changes in (wave speed) (wave frequency)
