Question

Find the frequency if the period is 15 us.

Answer 1

The frequency is $6.67\cdot 10^4 Hz$

Explanation:

For a periodic motion:

• The period (T) of the motion is the time it takes for the body to make one complete oscillation.
• The frequency (f) of the motion is the number of complete oscillations made in one second

Frequency and period are related by the equation:

$f=\frac{1}{T}$

where

f is the frequency

T is the period

For the motion in this problem, we have:

$T=15 \mu s = 15\cdot 10^{-6} s$ is the period

Therefore, the frequency is:

$f=\frac{1}{15\cdot 10^{-6}}=6.67\cdot 10^4 Hz$
