The period is the time taken by the wave to complete an oscillation. The frequency of the given sound is 500 Hz.
It is the time taken by the wave to complete an oscillation. The frequency is inversely proportional to the time:
[tex]f = \dfrac 1T[/tex]
Where,
[tex]f[/tex]- frequency
[tex]T[/tex] - period = 0.002 s
Put the value in the equation,
[tex]f = \dfrac 1{0.002}\\\\f = 500\rm \ Hz[/tex]
Therefore, the frequency of the given sound is 500 Hz.
