Unformatted text preview: f = 1/T. Therefore frequency is 100 Hz. Wavelength = c/f = 340/100) b. 100 m c. 34000 m d. Cannot tell from this information 4. A certain sound has a wavelength of 17 cm. What is the frequency of this sound? ** a. 2 Hz b. 20 Hz c. 200 Hz d. 2000 Hz (Use c = 34000 cm/s as wavelength is expressed in cm. Therefore f = 34000/17) 5. A certain sound has a wavelength of 340 m. How many cycles would this sound complete in 5 s? ** a. 68 b. 1700 c. 5 (First, calculate the frequency of this sound. f = 340/340 = 1 Hz. So this sound will complete 1 cycle in 1 second, and so 5 cycles in 5 seconds.) d. 1...
