To calculate the time taken by one oscillation (also known as the period) when a sound wave has a frequency of 1.5 kHz (kilohertz), you can use the formula:
Period (T) = 1 / Frequency (f)
In this case, the frequency is given as 1.5 kHz, which means 1.5 thousand cycles per second.
Substituting the value into the formula:
T = 1 / 1.5 kHz
To perform the calculation, it's helpful to convert the kilohertz value to hertz:
1 kHz = 1000 Hz
Therefore, 1.5 kHz is equivalent to 1500 Hz.
T = 1 / 1500 Hz
Calculating the period:
T = 0.0006667 seconds or approximately 0.667 milliseconds.
So, for a sound wave with a frequency of 1.5 kHz, the time taken by one oscillation (period) is approximately 0.667 milliseconds.
