Question

What is the oscillation period of your eardrum when you are listening to the A4 note on a piano (frequency 440 Hz)?

Answer 1

The period is the inverse of the frequence:

`T=(1)/(f)=(1)/(440)=0.0022\overline{72}`

Answer 2

T = 0.002 s.

Step-by-step explanation:

Given data:

Frequency,
`f = 440 \ \rm Hz`

The time period of oscillation of the eardrum can be expressed as,

`T = (1)/(f)`

`T = (1)/(440 \ \rm Hz)`

`T = 0.002 \ s.`
