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

Answer:

T = 0.002 s.

Explanation:

Given data:

Frequency, $f = 440 \ \rm Hz$

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

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

$T = \frac{1}{440 \ \rm Hz}$

$T = 0.002 \ s.$

Answer 2

The period is the inverse of the frequence:

$T=\dfrac{1}{f}=\dfrac{1}{440}=0.0022\overline{72}$
