A wave with a frequency of 2000 Hz has a period of a. 0.005 b. 20 c. 2000 d. 0.0005

The correct answer is a. 0.005.The period of a wave is the reciprocal of its frequency. It represents the time it takes for one complete cycle of the wave to pass a given point. The formula to calculate the period is: Given that the frequency of the wave is 2000 Hz, we can calculate the period as follows: Therefore, the correct answer is a. 0.005.
