state whether you can hear the above sound.​

Answer 1

Here's the required answer to your question

Answer 2

Answer: Frequency is 25000 Hz and it is inaudible.

Given: Time period of electric tuning fork 0.00004 sec.

To Find: Frequency and type of sound.

Explanation:

Step 1: The quantity of cycles or vibrations per unit of time is referred to as frequency.

The amount of time that a behavior lasts or a condition persists. Depending on the type of activity or situation under consideration, it may be measured in seconds or in millions of years.

Below equation provides the relationship between frequency and time period.

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

Where T = time period

and f = frequency

Time period = 0.00004 sec

And we know that frequency = 1/Time period.

Frequency = 1/0.00004 = 25000

Hence, frequency is 25000 Hz.

Step 2: Humans can detect sounds in a frequency range from about 20 Hz to 20 kHz. But as we get, it is 25000 which is out of range of audible frequency.

Hence, it is inaudible.
