A wave has a frequency of 5000 Hz.
<br><br>
Calculate the period of the wave.
<br>
Use the equation:
<br>
period = 1 / frequency
A wave has a frequency of 5000 Hz.
<br><br>
Calculate the period of the wave.
<br>
Use the equation:
<br>
period = 1 / frequency
How to approach this question
1. Identify the value for frequency from the question.
2. Substitute this value into the given equation.
3. Calculate the result and include the correct units for period.
Full Answer
period = 1 / 5000
period = 0.0002 s
The question provides the equation: period = 1 / frequency.
The frequency is given as 5000 Hz.
Substitute the value into the equation:
Period = 1 / 5000
Period = 0.0002 s
The unit for period is seconds (s).
Common mistakes
✗ Calculating frequency / 1 instead of 1 / frequency.\n✗ Forgetting the units (s) for period.\n✗ Writing the answer in standard form incorrectly (e.g., 2 x 10^3 instead of 2 x 10^-4).
