1. Print this page and then measure the wavelength and amplitude of this sine curve. Wavelength = mm Amplitude = mm 2. A child is swinging on a playground swing. If she completes one full cycle (i. e. back and forth one time) in 5 seconds, What is the frequency of the swing? What is the period? 3. The period of a 440 Hz sound is . 4. A marine weather station reports that waves along the shore are 10 seconds apart. The frequency of the waves is . 5. The sound of a mosquito is produced when it beats its wings at an average of 600 beats per second. What is the frequency of the sound waves? Assuming that the speed of sound is 343 m/s, what is the wavelength of the sound waves? 6. If a wave generator produces 10 pulses per second and the speed of the waves is 300 m/s, what is the wavelength of the waves? What happens to the wavelength if the frequency of the pulses is increased?
