Question

A quartz crystal vibrates with a frequency of 77,621 hz. what is the period of the crystal's motion?

Answer 1

Formula for period:

`T=(1)/(f)`

period(measured in seconds) = 1 / frequency(measured in hertz)

__________________________________________________________

Given:

`f=77,621Hz`

`T=?`

__________________________________________________________

Finding period:

`T=(1)/(f)`

`T=(1)/(77,621)`

__________________________________________________________

Answer:

`\fbox{T = 0.0000129}`
