Middle C on a typical musical instrument has a frequency of 264 Hz. How long does one complete oscillation take?

1. Period and frequency are reciprocals, so T = 1 / f. 2. T = 1 / 264 Hz, and 264 Hz means 264 cycles per second. 3. T = 3.79 x 10^-3 s. 4. Converting to milliseconds, 3.79 x 10^-3 s = 3.79 ms. 5. Reading the frequency itself as a time gives 264 ms, which is the trap in one option. _Source: OpenStax College Physics (CC BY 4.0), Ch 16 "Oscillatory Motion and Waves", section 16.2 Period and Frequency in Oscillations_
