Problem 1) The maximum frequency that humans can hear is roughly 20,000 Hz. a) Convert this frequency to kHz. (Show work here.) The frequency is kHz b) Find the period of this oscillation in seconds (5), milliseconds (ms), and microseconds (us). Problem 2) For the oscillation on the right, nd the period T in seconds and in milliseconds: T: 5: m5. Find the frequency of the oscillation in Hz and in kHz: f = Hz = kHz. What is the amplitude of the oscillation? Be sure to include the units. Amplitude = The period is s T = ms T = p5 10. i g 5 , amplitude (cm) 10 ._i_._._. 0 5 1 15 20 time (ms) Page 2 of4
